This happens only when there are spills happen in Unordered case. Doesn't happen when the ratios are adjusted tez.task.scale.memory.ratios="PARTITIONED_UNSORTED_OUTPUT:3,UNSORTED_INPUT:3,UNSORTED_OUTPUT:3,SORTED_OUTPUT:12,SORTED_MERGED_INPUT:12,PROCESSOR:1,OTHER:4"
This needs more investigation as it is hard to say if there is issue in hive/tez side for hashtable loading. Creating this as a placeholder for further investigation.
Scenario:
=======
1. hive trunk (mar 13 build)
2. Tez 0.7 master
3. TPCDS Query 17 @ 10 TB scale
