------------------------------
Summary: HS2 Lineage leakage with 16x concurrency tests
Key: HIVE-11220
URL: https://issues.apache.org/jira/browse/HIVE-11220
Project: Hive
Issue Type: Bug
Components: HiveServer2
Affects Versions: llap, 1.3.0
Reporter: Gopal V
Test scenario is the HS2 + LLAP, 16x concurrency of TPCDS queries which take
less than 4 seconds.
session.LineageState accumulates optimizer lineage info and HS2 OOMs due to the
amount of data being held in the SessionState, since the sessions are
continously being used without pause.
The issue seems to be triggered due to the volume of fast queries or the life
time of a single JDBC connection.
