Steven Hawkins resolved TEIID-339.
----------------------------------
Resolution: Done
The pushing of distinct (union) is handled in RuleCollapseSource. RulePushAggregates was
expanded to cover decomposing over aggregates using nested inline view queries. See
TestAggregatePushdown and TestAggregateProcessing

This is related to case 6652 and case 6653. It improves performance to push down
aggragate and distinct through union. If this is done before 5.5.3 release, we will
consider pulling the logics back to 5.5.3.
