Subject [jira] [Updated] (HDFS-2058) DataTransfer Protocol using protobufs
Date Fri, 10 Jun 2011 07:16:58 GMT

Todd Lipcon updated HDFS-2058:
------------------------------

    Attachment: hdfs-2058.txt

Here's what I hacked together. It passes the tests I've tried so far (TestHFlush, TestDataTransferProtocol,
TestWriteRead, and a few more).

Would need cleanup before commit, but I think this prototype shows this really isn't so hard,
we just need to sit down and do it.

> We've been talking about this for a long time... would be nice to use something like
protobufs or Thrift for some of our wire protocols.
> I knocked together a prototype of DataTransferProtocol on top of proto bufs that seems
to work.
