--------------------------------------
Summary: Hcat cli does not close SessionState
Key: HIVE-6726
URL: https://issues.apache.org/jira/browse/HIVE-6726
Project: Hive
Issue Type: Bug
Affects Versions: 0.13.0, 0.14.0
Reporter: Sushanth Sowmyan
Assignee: Sushanth Sowmyan
When running HCat E2E tests, it was observed that hcat cli left Tez sessions on
the RM which ultimately die upon timeout. Expected behavior is to clean the Tez
sessions immediately upon exit. This is causing slowness in system tests as
over time lot of orphan Tez sessions hang around.
On looking through code, it seems obvious in retrospect because HCatCli starts
a SessionState, but does not explicitly call close on them, exiting the jvm
through System.exit instead. This needs to be changed to explicitly call
SessionState.close() before exiting.
