Owen O'Malley updated HADOOP-2188: ---------------------------------- Fix Version/s: (was: 0.16.0) > RPC should send a ping rather than use client timeouts > ------------------------------------------------------ > > Key: HADOOP-2188 > URL: https://issues.apache.org/jira/browse/HADOOP-2188 > Project: Hadoop > Issue Type: Improvement > Components: ipc > Reporter: Owen O'Malley > Assignee: Owen O'Malley > Attachments: rpc-to.patch > > > Current RPC (really IPC) relies on client side timeouts to find "dead" > sockets. I propose that we have a thread that once a minute (if the > connection has been idle) writes a "ping" message to the socket. The client > can detect a dead socket by the resulting error on the write, so no client > side timeout is required. Also note that the ipc server does not need to > respond to the ping, just discard it. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
