Eric Yang commented on CHUKWA-679:
----------------------------------

By using webHDFS, we have the following benefits:

1. Ability to encrypt communication between chukwa agent and datanode.
2. Use the same security mechanism as Hadoop
3. Improved throughput in comparison to Hadoop RPC for data transfer.
4. Improves data block placement to partitioned more evenly base on size, across nodes to
improve mapreduce job processing.
