[teiid-issues] [JBoss JIRA] (TEIID-3977) Add support for EnableDependentJoins for Impala data sources

[Steven Hawkins (JIRA)]

Steven Hawkins commented on TEIID-3977:
---------------------------------------

Hive supports temporary tables, but Impala still does not.  The best that we could do is create a uniquely named internal table for Impala,  I don't think we should go down that route though.  [~asaji] what are your thoughts?
