--------------------------------

             Summary: Use netty to implement DatanodeWebHdfsMethods
                 Key: HDFS-7279
                 URL: https://issues.apache.org/jira/browse/HDFS-7279
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Haohui Mai
            Assignee: Haohui Mai


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.
