Michael Echevarria commented on TEIID-4858:
-------------------------------------------

Only difference I can see is the Execution Factory.  Simple returns quickly where Hive takes 30+ seconds.

> When querying a table through the hive translator the results take close to 30 seconds to return.
> When querying a table through jdbc default results take under 1 second to return.
> Both use the same underlying jboss server datasource.
