> 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.
