[jira] [Created] (MAPREDUCE-5103) Remove dead code QueueManager and JobEndNotifier

Robert Joseph Evans created MAPREDUCE-5103:
----------------------------------------------

             Summary: Remove dead code QueueManager and JobEndNotifier
                 Key: MAPREDUCE-5103
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5103
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: Robert Joseph Evans


There are a few classes that are dead or duplicate code at this point.  
org/apache/hadoop/mapred/JobEndNotifier.java

org/apache/hadoop/mapred/QueueManager.java
org/apache/hadoop/mapred/QueueConfigurationParser.java
org/apache/hadoop/mapred/DeprecatedQueueConfigurationParser.java

LocalRunner is currently using the JobEndNotifier, but there is a replacement for in in MRv2 org.apache.hadoop.mapreduce.v2.app.JobEndNotifier.  The two should be combined together and duplicate code removed.

There appears to only be one method called for the QueueManger and it appears to be setting a property that is not used any more, so it can be removed.
