Phil Zampino updated KNOX-1440:
-------------------------------
Fix Version/s: 1.2.0
> 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
> Priority: Major
> Fix For: 1.2.0
>
>
> 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.
> (FYI: the datanode dispatch is configured in the WEBHDFS service definition)
