Aurora Thrift Client

This project implements a Thrift based Java client for Apache Aurora scheduler, running on a Mesos cluster. This client has been developed with a focus of being integrated with Apache Airavata for job submission & monitoring

Requirements

In order to use this client, you must have the following:

• A Mesos cluster - running on any public cloud (eg: AWS) We have written ansible scripts to deploy a Mesos-Marathon cluster on any given cloud infrastructure. The scripts can be found in the modules/cloud/ansible-playbooks directory, with necessary steps.

• Aurora scheduler installed on this Mesos cluster. Follow instructions at: http://aurora.apache.org/documentation/latest/operations/installation/ to install Aurora components in the cluster - including the scheduler, and worker components.

Configuration

Please update the aurora-scheduler.properties file in src/main/resources directory with the following properties:

```
# aurora scheduler host-name
aurora.scheduler.host=mesos-master-1

# aurora scheduler port (http)
aurora.scheduler.port=8081

# aurora executor name
aurora.executor.name=AuroraExecutor

# mesos cluster name
mesos.cluster.name=example
```

Default values for some of the parameters are added to the properties file.

Operations supported

Currently the following operations are supported, but more will be added progressively.

• Submit a job to the Aurora scheduler Job can be AdHoc(one time) or a Service (long running)

• Get job details

• Get pending jobs & reason for why it is pending

• Kill tasks in a Job, or kill all tasks in a Job

Sample Code

The AuroraClientSample.java contains sample code on how to use the Client.
