Ted Yu commented on HBASE-3909:
-------------------------------

Skimmed the patch.
Some high level questions:
when configuration is updated, how would regions in transition pick up the changes ?
when configuration is updated and meanwhile master fails over, what would happen ?

Thanks

> I'm sure this issue exists already, at least as part of the discussion around making online schema edits possible, but no hard this having its own issue.  Ted started a conversation on this topic up on dev and Todd suggested we lookd at how Hadoop did it over in HADOOP-7001
