Major Description
Everything that this class does is delegated to a Shim class.
To make HIVE-4895 and HIVE-4896 smoother, we need to get rid of HCatMapRedUtil and make the calls directly to the Shim layer. It will make it easier because all org.apache.hcatalog classes will move to org.apache.hive.hcatalog classes thus making way to provide binary backwards compat. This class won't change it's name so it's more difficult to provide backwards compat. The org.apache.hadoop.mapred.TempletonJobTracker is not an issue since it goes away in HIVE-4460.
