Summary: FS based stats collection generates wrong results for tez
Key: HIVE-11863
URL: https://issues.apache.org/jira/browse/HIVE-11863
Project: Hive
Issue Type: Bug
Affects Versions: 1.3.0, 2.0.0
Reporter: Prasanth Jayachandran
FS based stats collection is the default way to collect stats. However, there
are some cases (involving unions) where it generates wrong results. Refer test
case in HIVE-11860 and compare test cli driver results against tez results.
Also it will be good to extend statsfs.q test case with union queries.
