Review request for hive and Xuefu Zhang.

Bugs: HIVE-8649

Repository: hive-git


First patch for HIVE-8649, to increase the number of reducers for spark based on some info
about the spark cluster.
We need to add a SparkListener to handle cluster status change if such events are supported
by spark.

Diffs (updated)
