John Sichi commented on HIVE-1215:
----------------------------------
We have tests for such queries, and we enable assertions in the junit ant task,
but we do not seem to be enabling assertions for the forked JVM's which execute
the plan. We should find a way to address this in order to get more coverage
for assertions (and also to expose any more bogus ones).
