> Currently the DN implements all related webhdfs functionality using jetty. As
> the current jetty version the DN used (jetty 6) lacks of fine-grained buffer
> and connection management, DN often suffers from long latency and OOM when
> its webhdfs component is under sustained heavy load.
> This jira proposes to implement the webhdfs component in DN using netty,
> which can be more efficient and allow more finer-grain controls on webhdfs.
