[jira] [Updated] (MAPREDUCE-6895) Job end notification not send due

-------------------------------------
Attachment: MAPREDUCE-6895.002.patch
Thanks [~leftnoteasy] and [~djp] for review.
Upload one patch to remove below lines.
{code}
// Do we need job-end notification?
if (userUrl == null) {
Log.getLog().info("Job end notification URL not set, skipping.");
return;
}
{code}
Personally I think it's better to keep it in case in future someone called notifier.notify(report) without MRJobConfig.MR_JOB_END_NOTIFICATION_URL set.
