Doug Cutting updated HDFS-892:
------------------------------
Attachment: HDFS-892.patch
Here's a first version of this. Default behaviour is unchanged. Passing Ant
-Dtest.hdfs.rpc.engine=org.apache.hadoop.ipc.AvroRpcEngine will cause Avro
reflection to be used on all NN protocols, and Avro-format RPC calls to be made
over a Hadoop RPC tunnel. Some but not all tests yet pass in this
configuration. The primary intent of this issue is to test that Avro reflect
can correctly characterize all of the Namenode's protocols.
> optionally use Avro for namenode RPC
