Owen O'Malley commented on HADOOP-182: -------------------------------------- Note that marking completed reduces of running jobs as failed is _really_ bad because if the file already exists, I believe the tip will fail, thereby killing the job. > lost task trackers should not update status of completed jobs > ------------------------------------------------------------- > > Key: HADOOP-182 > URL: http://issues.apache.org/jira/browse/HADOOP-182 > Project: Hadoop > Type: Bug > Components: mapred > Versions: 0.1.1 > Reporter: Owen O'Malley > Assignee: Owen O'Malley > Priority: Minor > Fix For: 0.3 > > When a Task Tracker is lost (by not sending a heartbeat for 10 minutes), the > JobTracker marks the tasks that were active on that node as failed. There are > two issues: > 1. No task from a completed or failed job should be modified. > 2. No reduces should be marked as failed, since their output is in dfs and > therefore not only on the dead node. -- 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
