Major Description
Had to patch up a few things to get hive to run queries on top of tez.
a) Hive calls getJobFile
b) NPE (getTaskProgress returns null)
c) NPE in getJob (which winds up calling downgrade on JobStatus, which in turn fails because getPriority returns null)
With these changes hive runs, although number of mappers/reducers is always displayed as 0 and no progress is reported.
