> Project: Hadoop HDFS
> Issue Type: Bug
> Components: nfs
> Affects Versions: 2.7.0

> Write and Commit responses directly write data to the channel instead of propagating it to the next immediate handler in the channel pipeline.
> Not following Netty channel pipeline model could be problematic. We don't know whether it could cause any resource leak or performance issue especially the internal pipeline implementation keeps changing with newer Netty releases.
