[jira] [Created] (HDFS-5755) Filesystem close blocks SystemExit if a DFS client is trying to talk to a nonexistent NN

------------------------------------

             Summary: Filesystem close blocks SystemExit if a DFS client is trying to talk to a nonexistent NN
                 Key: HDFS-5755
                 URL: https://issues.apache.org/jira/browse/HDFS-5755
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.2.0
            Reporter: Steve Loughran
            Priority: Minor


If a DFS client instance is spinning in a connection refused cycle, and you try to stop the process via System.exit(), the exit call does not complete until the client has actually given up. 

That is: you can't exit a process with a standard kill while a DFS client operation is blocking.
