Subject Re: Hive Replication

Hello,

Sorry for the delayed reply.

The way falcon replication works in this case is that it first exports the
table to a staging location and then it distcp to target cluster and then
it does an import. So if any updates happen after the export then they
won't be a part of the copy in the target.
