Li Bo commented on HDFS-7729:
-----------------------------
Thanks for your careful review.
1.the variable {{hasSentEndPacket}} is duplicated with {{byteCurBlock}},will
remove it in new patch.
2.{{testCopyOnWrite}} also fails on trunk code, I think the failure is not
caused by changes of DFSOutputStream. You can have a further check. I will
debug this problem tomorrow.
3.add Javadoc in new patch.
4.add logic check if it’s striping layout when doing hflush or hsync operation.
> Add logic to DFSOutputStream to support writing a file in striping layout

> 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.
