Victoria Markman updated DRILL-3045:
------------------------------------
Description:
The symptom is: we are running simple query of the form "select x from t where
dir0='xyz and dir1='2015-01-01';" partition pruning works for a while and then
it stops working.
Query does run (since we don't fail the query in the case when we failed to
prune) and return correct results.
