    Description

      This JIRA is for the input side changes moved out of HDFS-2149. EditLogInputStream has been changed to no longer be an InputStream implementation, but to return a stream of FSEditLogOp objects using readOp(). The upshot is that all that can ever be read from an EditLogInputStream is a op. No random hackery can be used to put other things in the stream. Version is now a property of the EditLogInputStream and retrieved using getVersion().
