A failing retry'able notification in JobEndNotifier can affect notifications of other jobs. -------------------------------------------------------------------------------------------
Key: MAPREDUCE-1688 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1688 Project: Hadoop Map/Reduce Issue Type: Bug Components: jobtracker Affects Versions: 0.20.1 Reporter: Vinod K V The JobTracker puts all the notification commands into a delay-queue. It has a single thread that loops through this queue and sends out the notifications. When it hits failures with any notification which is configured to be retired via {{job.end.retry.attempts}} and {{job.end.retry.interval}}, the notification is queued back again. A single notification with sufficiently large number of configured retries and which consistently fails will affect other notifications in the queue. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
