 The javadoc comment for {{renameMapOutputForReduce}} incorrectly refers to a 
 single map output directory, whereas this depends on LOCAL_DIRS.
 mapOutIndex should be set to subMapOutputFile.getOutputIndexFile()

Attachment: MAPREDUCE-5952.v04.patch

[~kasha], the reason the method was moved because it's static in nature (does 
not need any instance fields) and I needed to make it static for easier 
testability. {{EventHandler}} is not a static inner class. Making it static 
will also move other methods around. Here is v04 that avoids moving 
{{renameMapOutputForReduce}} but it will remain an instance method.

Attachment: MAPREDUCE-5952.v03.patch

bq. I must be missing something here. 
LocalContainerLauncher#renameMapOutputForReduce isn't called anywhere in 
non-test code.

[~kasha], no that was my rebase mistake. I replaced private 
renameMapOutputForReduce by a 'protected static', but the old method definition 
remained in the file due to the merge error. Attaching v03 with the private 
renameMapOutputForReduce finally deleted.
