IMPALA-5788: Fix agg node crash when grouping by nondeterministic exprs Fixed a bug where impala crashes during execution of an aggregation query using nondeterministic grouping expressions. This happens when it tries to rebuild a spilled partition that can fit in memory and rows get re-hashed to a partition other than the spilled one due to the use of nondeterministic expressions. Testing: Added a query test to verify successful execution.
