guifeng updated SPARK-19645:
----------------------------
Description:
We are trying to use Structured Streaming in product, however currently
there exists a bug refer to the process of streaming job restart.
The following is the concrete error message:

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 whose name is
"currentBatchId.delta". In my opinion, this is a bug. If you guy consider that
this is a bug also, I can fix it.
