> 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.
