Olga Shen commented on MAPREDUCE-1688:
--------------------------------------
MAPREDUCE-3028 only added timeout setting in
org.apache.hadoop.mapreduce.v2.app.JobEndNotifier.
Would you apply timeout setting to org.apache.hadoop.mapred.JobEndNotifier for
MRv1 users?
> 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, 1.0.0, 1.0.2, 1.0.3
> Reporter: Vinod Kumar Vavilapalli
> Assignee: Ravi Prakash
>
> 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.
