The RPC server Listener thread is a scalability bottleneck ----------------------------------------------------------
Key: HADOOP-6713 URL: https://issues.apache.org/jira/browse/HADOOP-6713 Project: Hadoop Common Issue Type: Improvement Components: ipc Affects Versions: 0.20.2, 0.20.1, 0.20.0 Reporter: dhruba borthakur Assignee: Dmytro Molkov The Hadoop RPC Server implementation has a single Listener thread that reads data from the socket and puts them into a call queue. This means that this single thread can pull RPC requests off the network only as fast as a single CPU can execute. This is a scalability bottlneck in our cluster. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
