Jimmy Xiang commented on HIVE-8362:
-----------------------------------

Looked into it and found sometimes the test failed with extra info in parallel.q.out (other than that Chao mentioned):
{noformat}
PREHOOK: query: DROP TABLE IF EXISTS src
PREHOOK: type: DROPTABLE
PREHOOK: Input: default@src
PREHOOK: Output: default@src
POSTHOOK: query: DROP TABLE IF EXISTS src
POSTHOOK: type: DROPTABLE
POSTHOOK: Input: default@src
POSTHOOK: Output: default@src
PREHOOK: query: DROP TABLE IF EXISTS src1
PREHOOK: type: DROPTABLE
PREHOOK: Input: default@src1
{noformat}

This is caused by the clean up script: data/scripts/q_test_cleanup.sql
We need to make sure the output of this cleanup script won't be dumpped into parallel.q.out.
