Tsz Wo (Nicholas), SZE updated HADOOP-6079:
-------------------------------------------

    Attachment: 6079_20090618.patch

6079_20090618.patch:
- serialize proxySource as DatanodeInfo only.
- change BalancerDatanode not to implement Writable since it is not used anywhere.

The existing TestBlockReplacement is already serializing proxySource as DatanodeInfo.  So, no new test is added.
