Haohui Mai created HDFS-7279: -------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
