Peter Cseh commented on OOZIE-2606: ----------------------------------- [~satishsaley], I've looked around in the Spark code. The Spark version is stored in a package object. It can be reached like this: {code} import org.apache.spark.package$; ... System.out.println(package$.MODULE$.SPARK_VERSION()); {code} It's there for both [Spark1|https://github.com/apache/spark/blob/branch-1.6/core/src/main/scala/org/apache/spark/package.scala#L46] and [Spark2|https://github.com/apache/spark/blob/branch-2.0/core/src/main/scala/org/apache/spark/package.scala#L91], but it's intended to use for internal documentation. It might not be a good idea to build upon it. Getting the information from the manifest seems more reliable at the moment. > Set spark.yarn.jars to fix Spark 2.0 with Oozie > ----------------------------------------------- > > Key: OOZIE-2606 > URL: https://issues.apache.org/jira/browse/OOZIE-2606 > Project: Oozie > Issue Type: Bug > Components: core > Affects Versions: 4.2.0 > Reporter: Jonathan Kelly > Assignee: Satish Subhashrao Saley > Labels: spark, spark2.0.0 > Fix For: 4.3.0 > > Attachments: OOZIE-2606-2.patch, OOZIE-2606.patch > > > Oozie adds all of the jars in the Oozie Spark sharelib to the > DistributedCache such that all jars will be present in the current working > directory of the YARN container (as well as in the container classpath). > However, this is not quite enough to make Spark 2.0 work, since Spark 2.0 by > default looks for the jars in assembly/target/scala-2.11/jars [1] (as if it > is a locally built distribution for development) and will not find them in > the current working directory. > To fix this, we can set spark.yarn.jars to *.jar so that it finds the jars in > the current working directory rather than looking in the wrong place.
