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.
