> LLAPStatusDriver might get stuck polling status from Yarn if the following
> happen in this order:
> * there was a running LLAP Yarn app previously which is now finished / killed
> * Yarn was restarted
> * LLAPStatusDriver is invoked before any new LLAP app gets kicked off
> * LLAPStatusDriver receives the old app ID, which is then cached in the Yarn
> serviceClient object (no evicition)
> * In the meantime if any new LLAP app gets kicked off, LLAPStatusDriver will
> not see it, as it constantly retries fetching info about the wrong, old app
> ID (this is because we don't create new serviceClient objects)
> {code:java}
