Steve Loughran created HADOOP-10219:
---------------------------------------

             Summary: org.apache.hadoop.ipc.Client.setupIOstreams() needs to check for {{ClientCache.stopClient}}
requested shutdowns 
                 Key: HADOOP-10219
                 URL: https://issues.apache.org/jira/browse/HADOOP-10219
             Project: Hadoop Common
          Issue Type: Bug
          Components: ipc
    Affects Versions: 2.2.0
            Reporter: Steve Loughran


When {{ClientCache.stopClient()}} is called to stop the IPC client, if the client
is blocked spinning due to a connectivity problem, it does not exit until the policy has timed
out -so the stopClient() operation can hang for an extended period of time.

This can surface in the shutdown hook of FileSystem.cache.closeAll()
