Jeff Whiting commented on ACCUMULO-378:
---------------------------------------

While thinking about replication master - master replication should also be considered as
it can have a large implications on how the replication is implemented.

> The use case here is where people have multiple data centers and need to replicate the
data in between them.  Accumulo can model this replication after the way that HBase currently
handles the replication as detailed here (http://hbase.apache.org/replication.html).  
> There will be one master Cluster and multiple slave clusters.  Accumulo will use the
Master-Push model to replicate the statements from the master clusters WAL to the various
slaves WALs.
