------------------------------------

             Summary: Create service in Master that handles replication "pushes"
                 Key: ACCUMULO-2581
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2581
             Project: Accumulo
          Issue Type: Sub-task
            Reporter: Josh Elser
             Fix For: 1.7.0


We likely want the Master to handle the coordination of reading the records of what data needs
to be replicated to the slave(s). We do not have the Master to perform the actual replication,
but to delegate out the tasks to the tservers in the master cluster, and simple track the
progress, success and failure of each "replication act". This will allow for a much more scalable
implementation.

This service should be able to grow and shrink as replication requests increase/decrease (but
yet retain configurable upper and lower bounds). It likely requires its own Thrift service
to manage the variety of responses that might come from an attempt to replicate data (failure,
success, partial success, etc).

This service would be the only process that removes replication entries from the persisted
store (table).
