[DRILL-3045] Drill is not partition pruning due to internal off-heap memory limit for planning phase

• Type: Bug
• Status: Closed
• Priority: Major
• Resolution: Fixed
• Affects Version/s: 1.0.0
• Fix Version/s: 1.2.0
• Component/s: Query Planning & Optimization

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.
