Kai Zheng commented on HDFS-7729:
---------------------------------
bq.this patch looks much better now ! Client striping logic is a complex piece
and I believe we are getting closer.
It's great ! Thanks [~zhz] for guiding Bo thru this. To get even closer,
[~libo-intel], would you please clean up, get the necessary left TODO items
done this phase and make it edible to commit. Possible to use erasure raw coder
API and the RS coder impl in HADOOP-11542 ? Do we have new tests for the
stripping ? Please run thoroughly existing tests to ensure we're not breaking.
Thanks.

> If client wants to directly write a file striping layout, we need to add some
> logic to DFSOutputStream. DFSOutputStream needs multiple DataStreamers to
> write each cell of a stripe to a remote datanode.
