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.
> In DataTransferProtocol, the serialization of proxySource is not consistent
