Subject [jira] Created: (CHUKWA-506) Add retry logic to MetricDataLoader
Date Wed, 04 Aug 2010 00:14:16 GMT
Add retry logic to MetricDataLoader
-----------------------------------

                 Key: CHUKWA-506
                 URL: https://issues.apache.org/jira/browse/CHUKWA-506
             Project: Chukwa
          Issue Type: Improvement
    Affects Versions: 0.4.0
            Reporter: William Bajzek
            Priority: Minor


When processing data in Chukwa, many steps along the way, when the encounter an error condition,
will attempt to reprocess the data a few times before giving up. This doesn't happen in post
processing (at least when using MetricDataLoader); for example if there is a SQLException
of any kind, it will move the data to the "inError" directory at which point it becomes AFAIK
a manual process to move the data back to be reprocessed, so it would be nice to retry a few
times in case the exception was transient (database was being bounced, or similar). 

I will attach a patch to be reviewed.
