Repair hangs if a neighbor has nothing to send 
-----------------------------------------------

                 Key: CASSANDRA-2797
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-2797
             Project: Cassandra
          Issue Type: Bug
          Components: Core
    Affects Versions: 0.7.6
            Reporter: Sylvain Lebresne
            Assignee: Sylvain Lebresne
            Priority: Minor
             Fix For: 0.7.7, 0.8.2
         Attachments: 0001-Always-initiate-streaming-transfer-to-notify-remote-.patch

This is actually a streaming problem. If a StreamOutSession has nothing to transfer (i.e,
no sstables have the requested ranges), it will not even initiate the transfer and simply
close the session right away. The problem is that if the session was initiated by a remote
end (through a StreamRequestMessage), the remote end will never be notified and never run
his callback.
