> 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.
