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

             Summary: Replication V2
                 Key: HBASE-14379
                 URL: https://issues.apache.org/jira/browse/HBASE-14379
             Project: HBase
          Issue Type: Umbrella
          Components: Replication
            Reporter: Andrew Purtell
             Fix For: 2.0.0


Replication V2 is a tear-down of exiting replication code to just the interfaces introduced
in HBASE-11367, then a rebuild around the following principles:
- No state in ZooKeeper. Introduce a new system table for tracking peers, queues, and log
positions. (Some discussion on HBASE-10295, probably will be replaced with a set of more focused
issues.)
- Simplified internal programming model based on iterators
- Administrative actions mediated by the master with support for security hooks (like HBASE-11392)
- Replication state persisted and communicated with protobuf (like HBASE-11393 but everywhere)
- Optional consideration for replicating schema as well as data (like HBASE-12947). May fall
out of scope.
- Detailed metrics
- Support for at least simple status checks and admin actions via UI and shell

There are a number of existing JIRAs that will eventually be closed as duplicate, wont fix,
or reparented here.
