Andrew Purtell commented on HBASE-11992:
----------------------------------------
bq. Tested upgrade scenarios before and after the patch.
So you started two clusters, one master and one RS each? That won't test
exactly the scenario of concern. Would it be possible for you to test again
with two clusters where at least two RSes are replicating in each? Only upgrade
the RSes, one at a time.
> Backport HBASE-11367 (Pluggable replication endpoint) to 0.98

> ReplicationSource tails the logs for each peer. HBASE-11367 introduces
> ReplicationEndpoint which is customizable per peer. ReplicationEndpoint is
> run in the same RS process and instantiated per replication peer per region
> server. Implementations of this interface handle the actual shipping of WAL
> edits to the remote cluster.
> This issue is for backporting HBASE-11367 to 0.98.
