ClientServiceDelegate tries really hard to getJobStatus from a job through retries. However, if an AuthorizationException occurs, it will always continue to fail no matter how many retries it makes. AuthorizationException is also thrown when mapred job -status is call on unsupported services like tez jobs. This jira will limit the negative effect on AMs in both scenarios.
Caused by: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): Protocol interface org.apache.hadoop.mapreduce.v2.api.MRClientProtocolPB is not known.
