Network ACLs can prevent AMs to ping the Job-end notification URL
-----------------------------------------------------------------
Key: MAPREDUCE-3382
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3382
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: applicationmaster, mrv2
Affects Versions: 0.23.0
Reporter: Vinod Kumar Vavilapalli
Fix For: 0.23.1
MAPREDUCE-3028 added support for job-end notification from MR AMs after the job
finishes. 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.
