Review request for hive and Xuefu Zhang.

Bugs: HIVE-9410

Repository: hive-git


The RemoteDriver does not contains added jar in it's classpath, so it would failed to desrialize
SparkWork due to NoClassFoundException. For Hive on MR, while use add jar through Hive CLI,
Hive add jar into CLI classpath(through thread context classloader) and add it to distributed
cache as well. Compare to Hive on MR, Hive on Spark has an extra RemoteDriver componnet, we
should add added jar into it's classpath as well.

Diffs (updated)
