> Query below fails with NULL pointer exception. 
> This bug is a request to investigate why 8GB of direct memory is not enough to execute
this query.
> General enhancement to fail properly when running out of memory is addressed in DRILL-2920
> Query below was executed on a single node with direct memory of 8GB and planner.slice_target
= 1. Table size is 100 rows (parquet file)
> Increasing direct memory to 20GB allowed query to finish and return results.
> Failing query:
