> STORM-3606 identified an issue where Hadoop's TGT auto renewal thread causes
> an exception and worker restart. The fix involved a lot of reflection calls
> to emulate the Hadoop code while avoiding launching this thread.
>
> It's possible Hadoop could change their code, causing this reflection to
> fail. To handle this case, we could instead allow Hadoop to launch this
> autorenewal thread, and have the worker catch the specific NPE from Hadoop in
> the exception handler.
