***UNCHECKED*** [jira] [Created] (KNOX-1440) WEBHDFS: retry should not be attempted for datanode write failures

Phil Zampino created KNOX-1440:
----------------------------------

             Summary: WEBHDFS: retry should not be attempted for datanode write failures
                 Key: KNOX-1440
                 URL: https://issues.apache.org/jira/browse/KNOX-1440
             Project: Apache Knox
          Issue Type: Improvement
          Components: Server
    Affects Versions: 1.1.0
            Reporter: Phil Zampino


For WEBHDFS invocations through Knox, if a *datanode* write fails with an IOException, the currently configured HA dispatch (DefaultHADispatch) attempts the write a second time.

HDFS dev says that it would be appropriate to more simply respond with the error, deferring the decision to retry to the client.

This may be resolved as a consequence of KNOX-1439 's  resolution, but it may mean that a different dispatch be configured for the datanode interaction.
