Chris Westin updated DRILL-2757:
--------------------------------
Description:
Check that the path through sort that notices low memory conditions and causes
the sort to spill ("out of memory condition management").
Also check to make sure we handle queries and fragment failures properly under
these conditions.
"hashjoin, hashagg, and topn use large amounts of memory,and may be unable to
complete if their memory needs can't be met; for all others, the idea is that
they can complete if they get their reservation"
