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

             Summary: Document practical use-cases for replication
                 Key: ACCUMULO-2901
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2901
             Project: Accumulo
          Issue Type: Improvement
          Components: replication
            Reporter: Josh Elser
            Assignee: Josh Elser
             Fix For: 1.7.0


Replication, while it is a cool feature, does have situations where it's not 100% foolproof
and isn't guaranteed to provide eventual consistency given all situations.

Document these cases, how they could be avoided with certain configuration, and any implications
of those configurations.

Short list
* Failure on ACK from peer to primary could result in re-replication
* Combiners might not be accurate
