[~hagleitn], could I bug you to have a quick look at this patch to see if this
is sufficient?

> 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.
