Streaming Edits to a Standby Name-Node.
---------------------------------------

                 Key: HADOOP-4539
                 URL: https://issues.apache.org/jira/browse/HADOOP-4539
             Project: Hadoop Core
          Issue Type: New Feature
          Components: dfs
            Reporter: Konstantin Shvachko
             Fix For: 0.20.0
         Attachments: StreamEditsToSNN.htm

Currently Secondary name-node acts as mere checkpointer.
Secondary name-node should be transformed into a standby name-node (SNN). 
The long term goal is to make it a warm standby. 
The purpose of this issue is to provide real time streaming of edits to SNN so that it contained
the up-to-date namespace state.
