> 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.
