[ http://issues.apache.org/jira/browse/HADOOP-181?page=comments#action_12427126 ] Yoram Arnon commented on HADOOP-181: ------------------------------------
Eric, we don't get many lost task trackers in our sort benchmark any more, so I don't expect a significant improvement. In other jobs though, we do get the occasional lost task tracker. While every such case is a bug when nothing 'real' happens (HW error, network etc.) hunting every last one of them down is going to take quite a while. Minimizing the damage caused by such a glitch would be welcome if it doesn't cause adverse side effects. > task trackers should not restart for having a late heartbeat > ------------------------------------------------------------ > > Key: HADOOP-181 > URL: http://issues.apache.org/jira/browse/HADOOP-181 > Project: Hadoop > Issue Type: Bug > Components: mapred > Reporter: Owen O'Malley > Assigned To: Devaraj Das > Fix For: 0.6.0 > > Attachments: lost-heartbeat.patch > > > TaskTrackers should not close and restart themselves for having a late > heartbeat. The JobTracker should just accept their current status. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
