Nice catch - this may be a bug we should fix.
There are 4 relevant properties in MR2:
Attempts: "mapreduce.job.end-notification.retry.attempts" and
Retries: "mapreduce.job.end-notification.retry.interval" and
I believe the configs of the latter of both of the above
classifications were meant to be added in as replacement names, but
the property names got added in wrong (as the former/older named ones)
in the XML.
Could you file a JIRA for this as well as there being an issue with
the word "seconds" in the description of retries? The code in MR2's
JobEndNotifier seems to expect seconds but uses it directly in
Thread.sleep(…) without making it milliseconds, which may be a bug we
need to fix as well, perhaps in a same issue as the configs ones.
