[LIVY-967][SERVER] Return session information with livy sessions APIs (#383) ## What changes were proposed in this pull request? Currently livy GET /Sessions doesn't return fields like driver-executor memory, spark configuration, etc. Ideally a session response should return all the values set in session request api call(POST /sessions). JIRA: https://issues.apache.org/jira/browse/LIVY-967 ## How was this patch tested? Verified manually by creating interactive session via REST API call in a local Yarn cluster. Also, we have updated the unit tests.
Apache Livy is an open source REST interface for interacting with Apache Spark from anywhere. It supports executing snippets of code or programs in a Spark context that runs locally or in Apache Hadoop YARN.
Pull requests are welcomed! But before you begin, please check out the Contributing section on the Community page of our website.
Guides and documentation on getting started using Livy, example code snippets, and Livy API documentation can be found at livy.incubator.apache.org.
To build Livy, you will need:
Debian/Ubuntu:
maven
package or maven3 tarball)Redhat/CentOS:
maven
package or maven3 tarball)MacOS:
Required python packages for building Livy:
To run Livy, you will also need a Spark installation. You can get Spark releases at https://spark.apache.org/downloads.html.
Livy requires Spark 2.4+. You can switch to a different version of Spark by setting the SPARK_HOME
environment variable in the Livy server process, without needing to rebuild Livy.
Livy is built using Apache Maven. To check out and build Livy, run:
git clone https://github.com/apache/incubator-livy.git cd incubator-livy mvn package
You can also use the provided Dockerfile:
git clone https://github.com/apache/incubator-livy.git cd incubator-livy/dev/docker docker build -t livy . docker run --rm -it -v $(pwd)/../../:/workspace -v $HOME/.m2:/root/.m2 livy mvn package
Note: The
docker run
command maps the maven repository to your host machine's maven cache so subsequent runs will not need to download dependencies.
By default Livy is built against Apache Spark 2.4.5, but the version of Spark used when running Livy does not need to match the version used to build Livy. Livy internally handles the differences between different Spark versions.
The Livy package itself does not contain a Spark distribution. It will work with any supported version of Spark without needing to rebuild.
