Comment: was deleted
(was: aBut, spark mater don't set rename options that support overwrite, so I
think rename will failed also. After use hadoop 2.6+ remain failed.)

> The bug can be easily reproduce when restart previous streaming job, and
> the main reason is that when restart streaming job spark will recompute WAL
> offsets and generate the same hdfs delta file(latest delta file generated
> before restart and named "currentBatchId.delta") . In my opinion, this is a
> bug. If you guy consider that this is a bug also, I can fix it.
