[jira] [Created] (HDFS-5405) Fix possible RetryCache hang for caching RPC handlers in FSNamesystem

Andrew Wang created HDFS-5405:
---------------------------------

             Summary: Fix possible RetryCache hang for caching RPC handlers in FSNamesystem
                 Key: HDFS-5405
                 URL: https://issues.apache.org/jira/browse/HDFS-5405
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: namenode
    Affects Versions: HDFS-4949
            Reporter: Andrew Wang
            Assignee: Andrew Wang


Related to the fix in HDFS-5299, we need to make sure that uncaught exceptions happen before {{RetryCache.waitForCompletion}}, or badly timed failovers can lead to a perma-hang.
