Satish Subhashrao Saley commented on OOZIE-2482:
------------------------------------------------
Setting up SPARK_HOME=. will work as well, but we need to make sure that
pyspark and py4j zip files are under $SPARK_HOME/python/lib/ directory as spark
will look for it in [this
code|https://github.com/apache/spark/blob/branch-1.6/yarn/src/main/scala/org/apache/spark/deploy/yarn/Client.scala#L1049-L1051].
Main reason for moving to spark 1.6.1 is the version mismatch errors I faced
while writing the tests.
{code}
Exception: Python in worker has different version 2.7 than that in driver

ta/minicluster/mapred/local/1_0/taskTracker/test/jobcache/job_0001/attempt_0001_m_000000_0/work/tmp/spark-f71bd1cd-72f6-458d-b3c2-930c5a0eeb00,
PySpark cannot run with different minor versions
{code}
[~rkanter] I agree with you regarding documenting the change and appropriate
error messages.
Also, if users are already using {{oozie.service.ShareLibService.mapping.file}}
for spark sharelib, then we can encourage them to add paths for pyspark and
py4j zip files in there. That way individual user does not need copy over the
zip files in workflow lib/ directory.
