Tsz Wo (Nicholas), SZE updated HADOOP-7547:
-------------------------------------------

    Hadoop Flags: [Incompatible change]

Mark this as an incompatible change since the signatures of compareTo(..) are 
changed.  Before this, the compareTo(..) methods take Object as a parameter and 
cast to the corresponding class.  After the patch, the compareTo(..) methods 
directly take the corresponding class as a parameter.

Patch looks good.  Some minor comments:
- Let's revert the changes in RecordTypeInfo and Record since they are 
deprecated.
- Need to update with trunk.

> Fix the warning in writable classes.[ WritableComparable is a raw type. 
> References to generic type WritableComparable<T> should be parameterized  ]
