mapreduce.job.end-notification settings
I was looking at:

http://hadoop.apache.org/docs/current/hadoop-mapreduce-client/hadoop-mapreduce-client-core/mapred-default.xml

And I noticed that there are some duplicate properties with different values and different descriptions:

mapreduce.job.end-notification.retry.attempts 0 Indicates how many times hadoop should attempt to contact the notification URL
mapreduce.job.end-notification.retry.interval 30000 Indicates time in milliseconds between notification URL retry calls
...
mapreduce.job.end-notification.retry.attempts 5 The number of times the submitter of the job wants to retry job end notification if it fails. This is capped by mapreduce.job.end-notification.max.attempts
mapreduce.job.end-notification.retry.interval 1 The number of seconds the submitter of the job wants to wait before job end notification is retried if it fails. This is capped by mapreduce.job.end-notification.max.retry.interval

Any idea which values and descriptions are correct?
