Subject [jira] Commented: (HBASE-2197) Start replication from a point in time
Date Wed, 10 Feb 2010 17:32:28 GMT

Andrew Purtell commented on HBASE-2197:
---------------------------------------

bq. Currently random reads have that problem where they can return older versions of the data
if a timestamp in the memstore is older than data in the store files.

That's a bug. Let's file a jira for it and fix it.

> 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.
