Konstantin Shvachko commented on HDFS-1467:
-------------------------------------------
I don't quite understand what is wrong. I see we pass the old block and the
newGs to
{{datanode.data.append(block, newGs, minBytesRcvd);}}
only after that we set newGs to the old block. Looks good to me so far.
> we can never successfully construct a pipeline for append with more than one
> datanode in it!
I can testify this had been tested. Can we try to trace it back - not to blame
anybody, but to restate the historical events.
May be Hairong can shed some light onto it.
