Scenario:
- Ran query_89 with TPC-DS @ 10 TB
- Additional setings : "--hiveconf tez.runtime.io.sort.mb=1800 --hiveconf tez.runtime.sort.threads=2
--hiveconf hive.tez.container.size=4096 --hiveconf tez.runtime.shuffle.memory-to-memory.enable=false
 --hiveconf hive.vectorized.execution.enabled=false"

Same query passes when hybrid grace hashtable is disabled "--hiveconf hive.mapjoin.hybridgrace.hashtable=false"
.
