Gunther Hagleitner commented on HIVE-10456:
-------------------------------------------
Summary of offline discussion w/ [~prasanth_j]:
- Probably best to check if hash table is in registry (on abort). If it is:
Ownership is shared, no need to clean up. If it isn't: MapJoinOp owns the table
container and need to clean (+ free mem).
> Grace Hash Join should not load spilled partitions on abort

> Grace Hash Join loads the spilled partitions to complete the join in
> closeOp(). This should not happen when closeOp with abort is invoked. Instead
> it should clean up all the spilled data.
