Description
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.
