***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.
