    Description

      Its more of a nuisance then a bug, but nevertheless

      16:16:48,709 ERROR pool-1-thread-1 ipc.Client:195 - Interrupted while waiting for clientExecutorto stop
      java.lang.InterruptedException

      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.
