imeplement DFSClient on top of thriftfs - this may require DFSClient or DN
protocol changes
-------------------------------------------------------------------------------------------
Key: HADOOP-4136
URL: https://issues.apache.org/jira/browse/HADOOP-4136
Project: Hadoop Core
Issue Type: New Feature
Components: contrib/thiftfs, dfs, fs
Reporter: Pete Wyckoff
Priority: Minor
Open up DFS Protocol to allow non-Hadoop DFS clients to implement reads/writes.
Obviously, the NN need not be changed because the thriftfs server will serve
up the same metadata - ie it's a bridge to the NN.
This is useful because if we can do this in Java using more open APIs, we could
do it in C++ or Python or Perl :)
Doing it in Java first makes sense because we already have the DFSClient - kind
of a proof of concept.
