[jira] [Created] (HADOOP-10585) Retry polices ignore interrupted exceptions

Daryn Sharp created HADOOP-10585:
------------------------------------

             Summary: Retry polices ignore interrupted exceptions
                 Key: HADOOP-10585
                 URL: https://issues.apache.org/jira/browse/HADOOP-10585
             Project: Hadoop Common
          Issue Type: Bug
          Components: ipc
    Affects Versions: 2.0.0-alpha, 3.0.0
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp
            Priority: Critical


Retry polices should not use {{ThreadUtil.sleepAtLeastIgnoreInterrupts}}.  This prevents {{FsShell}} commands from being aborted during retries.  It also causes orphaned webhdfs DN DFSClients to keep running after the webhdfs client closes the connection.  Jetty goes into a loop constantly sending interrupts to the handler thread.  Webhdfs retries cause multiple nodes to have these orphaned clients.  The DN cannot shutdown until orphaned clients complete.
