Andrew Purtell commented on HBASE-2197:
---------------------------------------
My expectation as a user is that I would turn on replication and then do a MR
job to transfer already stored data from the source cluster to the new peer. So
this is iterating over and streaming values, not shipping files. In this way I
would not miss any new edits because they are already replicating even as I am
bringing over the values persisted before replication started, with timestamps
preserved. But, I would also have my clocks NTP synchronized and I would not be
manually adjusting timestamps.
> Start replication from a point in time

> One way to set up a cluster for replication is to distcp all files then start
> the replication. We need a way to make sure we don't miss any edits by being
> able to start a process that reads old log files from a defined point in time
> and send them to a specific slave cluster and then catch up with normal
> replication.
