looks like a duplicate of HADOOP-10036. Certainly filed by same reporter, who
should have checked first.

The retries in this case were per-exception (see YARN RMProxy), but they don't
specify SaslException/GSSException anywhere. I am not sure if this is an issue
with retry policy setup in YARN, or in ipc.Client.
