> We see issues with RM trying to launch a container while a NM is restarting
> and we get exceptions like NMNotReadyException. While YARN-3842 added retry
> for other clients of NM (AMs mainly) its not used by AMLauncher in RM causing
> there intermittent errors to cause job failures. This can manifest during
> rolling restart of NMs.
