Haohui Mai updated HDFS-7279: ----------------------------- Attachment: HDFS-7279.001.patch > Use netty to implement DatanodeWebHdfsMethods > --------------------------------------------- > > Key: HDFS-7279 > URL: https://issues.apache.org/jira/browse/HDFS-7279 > Project: Hadoop HDFS > Issue Type: Improvement > Components: datanode, webhdfs > Reporter: Haohui Mai > Assignee: Haohui Mai > Attachments: HDFS-7279.000.patch, HDFS-7279.001.patch > > > 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)
