    [ https://issues.apache.org/jira/browse/MAPREDUCE-3382?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13184019#comment-13184019

Hudson commented on MAPREDUCE-3382:

Integrated in Hadoop-Hdfs-trunk #922 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk/922/])
    MAPREDUCE-3382. Enhanced MR AM to use a proxy to ping the job-end notification URL. Contributed
by Ravi Prakash.

Network ACLs can have an implication on this one - outgoing connections from the compute nodes
may be restricted in some settings and so job-end notification( that can originate from the
AMs which may run on random nodes in the cluster) may have issues.
