> It happens sporadically when stopping YarnClient.
> Looking at the code in Client's 'unrefAndCleanup' its not immediately obvious
> why and who throws the interrupt but in any event it should not be logged as
> ERROR. Probably a WARN with no stack trace.
> Also, for consistency and correctness you may want to Interrupt current
> thread as well.
