> "alter table .. concatenate" DDL command creates MR task by default. When hive cli is
launched with execution engine as tez, the scheduling of the MR task for file merging could
be delayed until tez session expiration. This happens because YARN will not have capacity
to launch another AppMaster for MR task. We should create tez task to overcome this. When
the execution engine is tez TezTask will be created else MRTask will be created.
