-------------------------------------------
Hello [~rkanter], [~rohini], [~satishsaley] I've noticed that the patch from
this issue removes **determineSparkJarsAndClasspath** method introduced in
OOZIE-2277 by [~rkanter].
Currently we are migrating our jobs from [CDH
5.7|http://archive.cloudera.com/cdh5/cdh/5/oozie-4.1.0-cdh5.7.0.releasenotes.html]
without this patch to CDH 5.12 that has this patch applied starting from [CDH
5.10|http://archive.cloudera.com/cdh5/cdh/5/oozie-4.1.0-cdh5.10.0.releasenotes.html]
and it seems that there is a regression, because all of our jobs which use
hdfs api internally started to fail with the following error in the oozie
launcher logs

So it seems that this patch prevents oozie from fullfilling spark classpath
correctly with hadoop libraries.
Could you please suggest how to provide spark job with
hadoop-configuration.jar. Should it and all the necessary dependencies be
placed within the lib directory of the workflow?

> Currently, we pass jars using --jars option while submitting spark job. Also,
> we add spark.yarn.dist.files option in case of yarn-client mode.
> Instead of that, we can have only --files option and pass on the files which
> are present in mapreduce.job.cache.files. While doing so, we make sure that
> spark won't make another copy of the files if files exist on the hdfs. We saw
> the issues when files are getting copied multiple times and causing

> Diagnostics: Resource
