Robert Kanter commented on OOZIE-2606:
--------------------------------------
ugh, why can't Spark just load jars from the classpath like everything else? :(
I bet [~satishsaley] is right and we'll have to do something like OOZIE-2547.
> 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
> Labels: spark, spark2.0.0
> Fix For: trunk
>
> Attachments: 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. [2]
