Zhe Zhang updated HDFS-7729:
----------------------------
Attachment: HDFS-7729-009.patch
I've updated the patch slightly to fix Jenkins test failures. I think the patch
works with all existing unit tests now. Will wait for another Jenkins run.
[~jingzhao] Given that Bo is still in holiday and the DataStreamer refactor in
trunk will take some more time, do you think we can commit this functional
patch first? Since we are close to finish a minimum NN prototype, this client
patch can help us do some preliminary end-to-end tests. When HDFS-7793 is in we
can do a follow-on JIRA.

> 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.
