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)
