> In earlier ACID integration patch CTAS was not supported. (previously I used a different
approach in which I created a new data operation type for INSERT ONLY, which got errored out
in TxnHandler. Later I changed that to INSERT which is working fine) As CTAS is working now,
the corresponding tests for it should be restored.
> Note we still have the same limitations for MM tables as Hive regular tables do in general:
> https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-CreateTableAsSelect(CTAS)
>  
> CTAS has these restrictions:
> The target table cannot be a partitioned table.
> The target table cannot be an external table.
> The target table cannot be a list bucketing table.
