Harsh J updated MAPREDUCE-4172:
-------------------------------

    Description: 
There are lots of warnings in the hadoop-mapreduce-project presently. We can 
clear almost all of this away:

* Unused imports
* Unused variables
** For loops that can be replaced with while instead to save an unused variable
* Unused methods
* Deprecation warnings where an alternative can be used (Especially 
SequenceFile reader/writer usage and MiniDFSCluster usage)
* Deprecation warnings where an alternative isn't clear (Especially 
MiniMRCluster usage and DistributedCache API usage where a Job object may not 
be available)
* Unchecked conversions
* Raw type usage
* (etc.)

I'm going to open one sub-task per sub-project we have, with patches attached 
to them.

There are lots of warnings (unused imports, unused variables, for loops that 
can be replaced with while instead to save a variable, unused methods, 
deprecation warnings where an alternative isn't clear, unchecked calls, raw 
types, etc.) in the hadoop-mapreduce-project presently. We can clear almost all 
of this away.

I'm going to open one sub-task per sub-project we have, with patches attached 
to them.
