------------------------------

             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.
