Kai Zheng commented on HDFS-7672:
---------------------------------
Thanks for taking care of this. As handling writing failure is essential to the
EC support in both DataNode and client (by HDFS-7344 and HDFS-7545), we have
already some discussion about it. Looks like we need to update the designs to
reflect the discussion. When we upload the initial codes or design there, would
you help review them and provide your thoughts then? I thought it will help to
clarify how to collaborate and avoid duplicate effort in this aspect.

> For (6, 3)-Reed-Solomon, a client writes to 6 data blocks and 3 parity blocks
> concurrently. We need to handle datanode or network failures when writing a
