> Notice that the main thread appaars to be killing statestore, but fails to
> kill impalad. Notice that a message appears that says that all impalads are
> running in the midst of the code that tries to shut down the cluster. Is this
> test multi-threaded? Is there more than one “main thread” Are these main
> threads working at cross purposes? What recent change may have caused this?
> Also, looks like the script is sending signal 10 (SIGUSR1) while the
> statestore (in its log) says it got a SIGTERM (15):
> {noformat}

> {noformat}
> Not terribly familiar with this area of the product, so bumping it over to
> the BE team.
