to look at the new patch set (#5).
Change subject: IMPALA-5586: Null-aware anti-join can take a long time to cancel
......................................................................
IMPALA-5586: Null-aware anti-join can take a long time to cancel
Queries with a null-aware anti-join joining on a large number of NULLs
can take a long time to cancel if threads are stuck in
PartitionedHashJoinNode::EvaluateNullProbe(). This change adds the
RETURN_IF_CANCELLED macro to the function.
Testing:
Added logs to PartitionedHashJoinNode::EvaluateNullProbe() and made sure
that the function returns right away on cancellation.
