---++ Oozie Web Services API, V1 (Workflow, Coordinator, And Bundle)

The Oozie Web Services API is a HTTP REST JSON API.

All responses are in =UTF-8=.

Assuming Oozie is running at =OOZIE_URL=, the following web services end points are supported:

   * <OOZIE_URL>/versions
   * <OOZIE_URL>/v1/admin
   * <OOZIE_URL>/v1/job
   * <OOZIE_URL>/v1/jobs
   * <OOZIE_URL>/v2/job
   * <OOZIE_URL>/v2/jobs
   * <OOZIE_URL>/v2/admin
   * <OOZIE_URL>/v2/sla

Documentation on the API is below; in some cases, looking at the corresponding command in the
[[DG_CommandLineTool][Command Line Documentation]] page will provide additional details and examples.  Most of the functionality
offered by the Oozie CLI is using the WS API. If you export <code>OOZIE_DEBUG</code> then the Oozie CLI will output the WS API
details used by any commands you execute. This is useful for debugging purposes to or see how the Oozie CLI works with the WS API.

---+++ Versions End-Point

---+++ Job and Jobs End-Points

_Modified in Oozie v1 WS API_

These endpoints are for submitting, managing and retrieving information of workflow, coordinator, and bundle jobs.

---++++ Job Submission

---++++ Standard Job Submission

An HTTP POST request with an XML configuration as payload creates a job.

The type of job is determined by the presence of one of the following 3 properties:

   * =oozie.wf.application.path= : path to a workflow application directory, creates a workflow job
   * =oozie.coord.application.path= : path to a coordinator application file, creates a coordinator job
   * =oozie.bundle.application.path= : path to a bundle application file, creates a bundle job
   
Or, if none of those are present, the jobtype parameter determines the type of job to run. It can either be mapreduce or pig.

*Request:*

<verbatim>
POST /oozie/v1/jobs
Content-Type: application/xml;charset=UTF-8
.
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <property>
        <name>user.name</name>
        <value>bansalm</value>
    </property>
    <property>
        <name>oozie.wf.application.path</name>
        <value>hdfs://foo:8020/user/bansalm/myapp/</value>
    </property>
    ...
</configuration>
</verbatim>

*Response:*

<verbatim>
HTTP/1.1 201 CREATED
Content-Type: application/json;charset=UTF-8
.
{
  id: "job-3"
}
</verbatim>

A created job will be in =PREP= status. If the query string parameter 'action=start' is provided in 
the POST URL, the job will be started immediately and its status will be =RUNNING=.

Coordinator jobs with start time in the future they will not create any action until the start time 
happens.

A coordinator job will remain in =PREP= status until it's triggered, in which case it will change to =RUNNING= status.
The 'action=start' parameter is not valid for coordinator jobs.

---++++ Proxy MapReduce Job Submission

You can submit a Workflow that contains a single MapReduce action without writing a workflow.xml. Any required Jars or other files
must already exist in HDFS.

The following properties are required; any additional parameters needed by the MapReduce job can also be specified here:
   * =fs.default.name=: The NameNode
   * =mapred.job.tracker=: The JobTracker
   * =mapred.mapper.class=: The map-task classname
   * =mapred.reducer.class=: The reducer-task classname
   * =mapred.input.dir=: The map-task input directory
   * =mapred.output.dir=: The reduce-task output directory
   * =user.name=: The username of the user submitting the job
   * =oozie.libpath=: A directory in HDFS that contains necessary Jars for your job
   * =oozie.proxysubmission=: Must be set to =true=

---++++ Proxy Pig Job Submission

You can submit a Workflow that contains a single Pig action without writing a workflow.xml.  Any required Jars or other files must
already exist in HDFS.

The following properties are required:
   * =fs.default.name=: The NameNode
   * =mapred.job.tracker=: The JobTracker
   * =user.name=: The username of the user submitting the job
   * =oozie.pig.script=: Contains the pig script you want to run (the actual script, not a file path)
   * =oozie.libpath=: A directory in HDFS that contains necessary Jars for your job
   * =oozie.proxysubmission=: Must be set to =true=

The following properties are optional:
   * =oozie.pig.script.params.size=: The number of parameters you'll be passing to Pig
   required =oozie.pig.script.params.n=: A parameter (variable definition for the script) in 'key=value' format, the 'n' should be an integer starting with 0 to indicate the parameter number
   * =oozie.pig.options.size=: The number of options you'll be passing to Pig
   * =oozie.pig.options.n=: An argument to pass to Pig, the 'n' should be an integer starting with 0 to indicate the option number

The =oozie.pig.options.n= parameters are sent directly to Pig without any modification unless they start with =-D=, in which case
they are put into the <code><configuration></code> element of the action.

In addition to passing parameters to Pig with =oozie.pig.script.params.n=, you can also create a properties file on HDFS and
reference it with the =-param_file= option in =oozie.pig.script.options.n=; both are shown in the following example.

   * =mapred.job.tracker=: The JobTracker
   * =user.name=: The username of the user submitting the job
   * =oozie.hive.script=: Contains the hive script you want to run (the actual script, not a file path)
   * =oozie.libpath=: A directory in HDFS that contains necessary Jars for your job
   * =oozie.proxysubmission=: Must be set to =true=

The following properties are optional:
   * =oozie.hive.script.params.size=: The number of parameters you'll be passing to Hive
   * =oozie.hive.script.params.n=: A parameter (variable definition for the script) in 'key=value' format, the 'n' should be an integer starting with 0 to indicate the parameter number

---++++ Managing a Job

A HTTP PUT request starts, suspends, resumes, kills, update or dryruns a job.

*Request:*

<verbatim>
PUT /oozie/v1/job/job-3?action=start
</verbatim>

*Response:*

<verbatim>
HTTP/1.1 200 OK
</verbatim>

Valid values for the 'action' parameter are 'start', 'suspend', 'resume', 'kill', 'dryrun', 'rerun', and 'change'.

Rerunning and changing a job require additional parameters, and are described below:

---+++++  Re-Running a Workflow Job

A workflow job in =SUCCEEDED=, =KILLED= or =FAILED= status can be partially rerun specifying a list
of workflow nodes to skip during the rerun. All the nodes in the skip list must have complete its
execution.

The rerun job will have the same job ID.

A rerun request is done with a HTTP PUT request with a =rerun= action.

*Request:*

<verbatim>
PUT /oozie/v1/job/job-3?action=rerun
Content-Type: application/xml;charset=UTF-8
.
<?xml version="1.0" encoding="UTF-8"?>

</verbatim>

*Response:*

<verbatim>
HTTP/1.1 200 OK
</verbatim>

---+++++ Re-Running a coordinator job

A coordinator job in =RUNNING= =SUCCEEDED=, =KILLED= or =FAILED= status can be partially rerun by specifying the coordinator actions
to re-execute.

A rerun request is done with an HTTP PUT request with a =coord-rerun= =action=.

The =type= of the rerun can be =date= or =action=.

The =scope= of the rerun depends on the type:
* =date=: a comma-separated list of date ranges. Each date range element is specified with dates separated by =::=
* =action=: a comma-separated list of action ranges. Each action range is specified with two action numbers separated by =-=

The =refresh= parameter can be =true= or =false= to specify if the user wants to refresh an action's input and output events.

The =nocleanup= parameter can be =true= or =false= to specify is the user wants to cleanup output events for the rerun actions.

*Request:*

<verbatim>
PUT /oozie/v1/job/job-3?action=coord-rerun&type=action&scope=1-2&refresh=false&nocleanup=false
.
</verbatim>

or 

<verbatim>

.
</verbatim>

*Response:*

<verbatim>
HTTP/1.1 200 OK
</verbatim>

---+++++ Re-Running a bundle job

A coordinator job in =RUNNING= =SUCCEEDED=, =KILLED= or =FAILED= status can be partially rerun by specifying the coordinators to
re-execute.

A rerun request is done with an HTTP PUT request with a =bundle-rerun= =action=.

A comma separated list of coordinator job names (not IDs) can be specified in the =coord-scope= parameter.

The =date-scope= parameter is a comma-separated list of date ranges. Each date range element is specified with dates separated
by =::=. If empty or not included, Oozie will figure this out for you

The =refresh= parameter can be =true= or =false= to specify if the user wants to refresh the coordinator's input and output events.

The =nocleanup= parameter can be =true= or =false= to specify is the user wants to cleanup output events for the rerun coordinators.

*Request:*

<verbatim>
PUT /oozie/v1/job/job-3?action=bundle-rerun&coord-scope=coord-1&refresh=false&nocleanup=false
.
</verbatim>

*Response:*

<verbatim>
HTTP/1.1 200 OK
</verbatim>


---+++++ Changing endtime/concurrency/pausetime of a Coordinator Job

A coordinator job not in =KILLED= status can have it's endtime, concurrency, or pausetime changed.

A change request is done with an HTTP PUT request with a =change= =action=.

The =value= parameter can contain any of the following:
* endtime: the end time of the coordinator job.
* concurrency: the concurrency of the coordinator job.
* pausetime: the pause time of the coordinator job.

Multiple arguments can be passed to the =value= parameter by separating them with a ';' character.

If an already-succeeded job changes its end time, its status will become running.

*Request:*

<verbatim>
PUT /oozie/v1/job/job-3?action=change&value=endtime=2011-12-01T05:00Z

*Getting all the Workflows corresponding to a Coordinator Action:*

A coordinator action kicks off different workflows for its original run and all subsequent reruns.
Getting a list of those workflow ids is a useful tool to keep track of your actions' runs and
to go debug the workflow job logs if required. Along with ids, it also lists their statuses,
and start and end times for quick reference.

Both v1 and v2 API are supported. v0 is not supported.

<verbatim>
GET /oozie/v2/job/0000001-111219170928042-oozie-joe-C@1?show=allruns
</verbatim>

*Response*

<verbatim>
HTTP/1.1 200 OK
Content-Type: application/json;charset=UTF-8

{"workflows":[
    {
        "startTime":"Mon, 24 Mar 2014 23:40:53 GMT",

        "status":"SUCCEEDED",
        "endTime":"Mon, 24 Mar 2014 23:44:24 GMT"
    }
]}
</verbatim>

An alternate API is also available for the same output. With this API, one can pass the coordinator *JOB* Id
followed by query params - type=action and scope=<action-number>. One single action number can be passed at a time.

<verbatim>
GET /oozie/v2/job/0000001-111219170928042-oozie-joe-C?show=allruns&type=action&scope=1
</verbatim>

*Retrieve a subset of actions*

Query parameters, =offset= and =length= can be specified with a workflow job to retrieve specific actions. Default is offset=0, len=1000
<verbatim>
GET /oozie/v1/job/0000002-130507145349661-oozie-joe-W?show=info&offset=5&len=10
</verbatim>
Query parameters, =offset=, =length=, =filter= can be specified with a coordinator job to retrieve specific actions. 
Query parameter, =order= with value "desc" can be used to retrieve the latest coordinator actions materialized instead of actions from @1.
Query parameters =filter= can be used to retrieve coordinator actions matching specific status.
Default is offset=0, len=0 for v2/job (i.e., does not return any coordinator actions) and offset=0, len=1000 with v1/job and v0/job.
So if you need actions to be returned with v2 API, specifying =len= parameter is necessary.
Default =order= is "asc".
<verbatim>
GET /oozie/v1/job/0000001-111219170928042-oozie-joe-C?show=info&offset=5&len=10&filter=status%3DKILLED&order=desc
</verbatim>
Note that the filter is URL encoded, its decoded value is <code>status=KILLED</code>.
<verbatim>
GET /oozie/v1/job/0000001-111219170928042-oozie-joe-C?show=info&filter=status%21%3DSUCCEEDED&order=desc
</verbatim>
This retrieves coordinator actions except for SUCCEEDED status, which is useful for debugging.

---++++ Filtering the server logs with logfilter options
User can provide multiple option to filter logs using -logfilter opt1=val1;opt2=val1;opt3=val1. This can be used to fetch only just logs of interest faster as fetching Oozie server logs is slow due to the overhead of pattern matching.

<verbatim>
GET /oozie/v1/job/0000003-140319184715726-oozie-puru-C?show=log&logfilter=limit=3;loglevel=WARN
</verbatim>


Refer to the [[DG_CommandLineTool#Filtering_the_server_logs_with_logfilter_options][Filtering the server logs with logfilter options]] for more details.


---++++ Job graph

An =HTTP GET= request returns the image of the workflow DAG (rendered as a PNG image).
   * The nodes that are being executed are painted yellow
   * The nodes that have successfully executed are painted green
   * The nodes that have failed execution are painted red
   * The nodes that are yet to be executed are pained gray
   * An arc painted green marks the successful path taken so far
   * An arc painted red marks the failure of the node and highlights the _error_ action
   * An arc painted gray marks a path not taken yet

*Request:*
<verbatim>
GET /oozie/v1/job/job-3?show=graph[&show-kill=true]
</verbatim>

*Response:*
<verbatim>
HTTP/1.1 200 OK
Content-Type: image/png
Content-Length: {image_size_in_bytes}

{image_bits}
</verbatim>

The optional =show-kill= parameter shows =kill= node in the graph. Valid values for this parameter are =1=, =yes=, and =true=. This parameter has no effect when workflow fails and the failure node leads to the =kill= node; in  that case =kill= node is shown always.

The node labels are the node names provided in the workflow XML.

This API returns =HTTP 400= when run on a resource other than a workflow, viz. bundle and coordinator.

---++++ Job Status

An =HTTP GET= request that returns the current status (e.g. =SUCCEEDED=, =KILLED=, etc) of a given job.  If you are only interested
in the status, and don't want the rest of the information that the =info= query provides, it is recommended to use this call
as it is more efficient.

*Request*
<verbatim>
GET /oozie/v2/job/0000000-140908152307821-oozie-rkan-C?show=status
</verbatim>

*Response*

<verbatim>
HTTP/1.1 200 OK
Content-Type: application/json;charset=UTF-8
.
{
  "status" : "SUCCEEDED"
}
</verbatim>

It accepts any valid Workflow Job ID, Coordinator Job ID, Coordinator Action ID, or Bundle Job ID.

---++++ Changing job SLA definition and alerting
An =HTTP PUT= request to change job SLA alert status/SLA definition.

   * All sla commands takes actions-list or date parameter.
   * =date=: a comma-separated list of date ranges. Each date range element is specified with dates separated by =::=
   * =action-list=: a comma-separated list of action ranges. Each action range is specified with two action numbers separated by =-=
   * For bundle jobs additional =coordinators= (coord_name/id) parameter can be passed.
   * Sla change command need extra parameter =value= to specify new sla definition.


   * Changing SLA definition
   SLA definition of should-start, should-end, nominal-time and max-duration can be changed.

<verbatim>
PUT /oozie/v2/job/0000003-140319184715726-oozie-puru-C?action=sla-change&value=<key>=<value>;...;<key>=<value>

</verbatim>
Will disable SLA alert for actions whose nominal time is in-between 2009-02-01T00:10Z 2009-03-01T00:10Z (inclusive).


<verbatim>
PUT /oozie/v1/job/0000004-140319184715726-oozie-puru-B?action=sla-disable&date=2009-02-01T00:10Z::2009-03-01T00:10Z&coordinators=abc
</verbatim>
For bundle jobs additional coordinators (list of comma separated coord_name/id) parameter can be passed.

   * Enabling SLA alert

<verbatim>
PUT /oozie/v2/job/0000003-140319184715726-oozie-puru-C?action=sla-enable&action-list=1,14,17-20

</verbatim>

No action information is returned when querying for multiple jobs.

The syntax for the filter is <verbatim>[NAME=VALUE][;NAME=VALUE]*</verbatim>

Valid filter names are:

   * name: the application name from the workflow/coordinator/bundle definition
   * user: the user who submitted the job
   * group: the group for the job (support for the group filter is discontinued. version: 3.2.0 OOZIE-228).
   * id: the id of the workflow/coordinator/bundle job
   * status: the status of the job
   * startCreatedTime : the start of the window about workflow job's created time
   * endCreatedTime : the end of above window
   * sortby: order the results. Supported values for =sortby= are: =createdTime= and =lastModifiedTime=

The query will do an AND among all the filter names.

The query will do an OR among all the filter values for the same name. Multiple values must be specified as different
name value pairs.

Additionally the =offset= and =len= parameters can be used for pagination. The start parameter is base 1.

Moreover, the =jobtype= parameter could be used to determine what type of job is looking for.
The valid values of job type are: =wf=, =coordinator= or =bundle=.

startCreatedTime and endCreatedTime should be specified either in *ISO8601 (UTC)* format *(yyyy-MM-dd'T'HH:mm'Z')* or
a offset value in days or hours or minutes from the current time. For example, -2d means the (current time - 2 days),
-3h means the (current time - 3 hours), -5m means the (current time - 5 minutes).

---++++ Jobs information using Bulk API

A HTTP GET request retrieves a bulk response for all actions, corresponding to a particular bundle, that satisfy user specified criteria.
This is useful for monitoring purposes, where user can find out about the status of downstream jobs with a single bulk request.
The criteria are used for filtering the actions returned. Valid options (_case insensitive_) for these request criteria are:

   * *bundle*: the application name from the bundle definition
   * *coordinators*: the application name(s) from the coordinator definition.
   * *actionStatus*: the status of coordinator action (Valid values are WAITING, READY, SUBMITTED, RUNNING, SUSPENDED, TIMEDOUT, SUCCEEDED, KILLED, FAILED)
   * *startCreatedTime*: the start of the window you want to look at, of the actions' created time
   * *endCreatedTime*: the end of above window
   * *startScheduledTime*: the start of the window you want to look at, of the actions' scheduled i.e. nominal time.
   * *endScheduledTime*: the end of above window

Specifying 'bundle' is REQUIRED. All the rest are OPTIONAL but that might result in thousands of results depending on the size of your job. (pagination comes into play then)

If no 'actionStatus' values provided, by default KILLED,FAILED will be used.
For e.g if the query string is only "bundle=MyBundle", the response will have all actions (across all coordinators) whose status is KILLED or FAILED

The query will do an AND among all the filter names, and OR among each filter name's values.

The syntax for the request criteria is <verbatim>[NAME=VALUE][;NAME=VALUE]*</verbatim>

For 'coordinators' and 'actionStatus', if user wants to check for multiple values, they can be passed in a comma-separated manner.
*Note*: The query will do an OR among them. Hence no need to repeat the criteria name

All the time values should be specified in *ISO8601 (UTC)* format i.e. *yyyy-MM-dd'T'HH:mm'Z'*

Additionally the =offset= and =len= parameters can be used as usual for pagination. The start parameter is base 1.

If you specify a coordinator in the list, that does not exist, no error is thrown; simply the response will be empty or pertaining to the other valid coordinators.
However, if bundle name provided does not exist, an error is thrown.

*Request:*

<verbatim>
GET /oozie/v1/jobs?bulk=bundle%3Dmy-bundle-app;coordinators%3Dmy-coord-1,my-coord-5;actionStatus%3DKILLED&offset=1&len=50
</verbatim>

Note that the filter is URL encoded, its decoded value is <code>user=chitnis</code>. If typing in browser URL, one can type decoded value itself i.e. using '='

---++ Oozie Web Services API, V2 (Workflow , Coordinator And Bundle)

The Oozie Web Services API is a HTTP REST JSON API.

All responses are in =UTF-8=.

Assuming Oozie is running at =OOZIE_URL=, the following web services end points are supported:

   * <OOZIE_URL>/versions
   * <OOZIE_URL>/v2/admin
   * <OOZIE_URL>/v2/job
   * <OOZIE_URL>/v2/jobs

*Changes in v2 job API:*

There is a difference in the JSON format of Job Information API (*/job) particularly for map-reduce action.
No change for other actions.
In v1, externalId and consoleUrl point to spawned child job ID, and exteranlChildIDs is null in map-reduce action.
In v2, externalId and consoleUrl point to launcher job ID, and exteranlChildIDs is spawned child job ID in map-reduce action.

v2 supports retrieving of JMS topic on which job notifications are sent

*REST API URL:*

<verbatim>
GET http://localhost:11000/oozie/v2/job/0000002-130507145349661-oozie-vira-W?show=jmstopic
</verbatim>

*Changes in v2 admin API:*

v2 adds support for retrieving JMS connection information related to JMS notifications.

*REST API URL:*

<verbatim>
GET http://localhost:11000/oozie/v2/admin/jmsinfo
</verbatim>

v2/jobs remain the same as v1/jobs
