Zhe Zhang commented on HDFS-7729:
---------------------------------
In my tests I set {{cellSize}} to a smaller value (1024) and got
IndexOutOfBound error in {{encode}}. [~libo-intel] could you take a look when
you resume work on this JIRA (after HDFS-7793)?

> 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.
