Subject [jira] Created: (HDFS-1054) Make sleep after failure in nextBlockOutputStream smarter and configurable
Date Sun, 21 Mar 2010 08:11:27 GMT
Make sleep after failure in nextBlockOutputStream smarter and configurable
--------------------------------------------------------------------------

                 Key: HDFS-1054
                 URL: https://issues.apache.org/jira/browse/HDFS-1054
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs client
    Affects Versions: 0.22.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon


If DFSOutputStream fails to create a pipeline, it currently sleeps 6 seconds before retrying.
I don't see a great reason to wait at all, much less 6 seconds (especially now that HDFS-630
ensures that a retry won't go back to the bad node). We should at least make it configurable,
and perhaps something like backoff makes some sense.
