[LIVY-399][TEST] Enable real test for PySpark and SparkR interpreters Currently because we lack pyspark and sparkr dependencies in our environment, so we neglect the pyspark and sparkr integration tests, here propose a way to enable these integration tests. The solution is mainly borrowed from Zeppelin - to download Spark binary before integration tests, so that we will have a complete Spark environment to do the test. Because of this several modules like minicluster-dependencies are not required, so here removed such modules. Besides, we proposed to remove real test implementations, since we never used real test before and it mainly did what scripts should do with Scala code, which makes it hard to maintain. Also for now mini-cluster test is quite close to real test, so it is not so useful to still keep real test. Author: jerryshao <sshao@hortonworks.com> Closes #49 from jerryshao/LIVY-399.
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 at least Spark 1.6 and supports both Scala 2.10 and 2.11 builds of Spark, Livy will automatically pick repl dependencies through detecting the Scala version of Spark.
Livy also supports Spark 2.0+ for both interactive and batch submission, you could seamlessly switch to different versions of Spark through SPARK_HOME
configuration, 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 livy mvn package
By default Livy is built against Apache Spark 1.6.2, but the version of Spark used when running Livy does not need to match the version used to build Livy. Livy internally uses reflection to mitigate the gaps between different Spark versions, also Livy package itself does not contain a Spark distribution, so it will work with any supported version of Spark (Spark 1.6+) without needing to rebuild against specific version of Spark.
