Kai Zheng commented on HDFS-9603:
---------------------------------
bq. Agreed that checksum is an important perspective before release. I'll
speedup the review.
Thanks Zhe! It should be much helpful.
bq. Right, hflush/hsync are unrelated to coder details. I was only suggesting
that hflush/hsync should have higher priority than the task in this JIRA.
Oh, I got the point, and agree. Can adding more hands on the hflush/hsync task
will do any help? Anyway it's a good idea and wise to focus on must-have tasks
first and release the master feature out.

> According to design, {{ErasureCoder}} is responsible to encode/decode a block
> group. Currently however, we directly use {{RawErasureCoder}} to do the work,
> e.g. in {{DFSStripedOutputStream}}. This task attempts to encapsulate
> {{RawErasureCoder}} to comply with the design.
