Subject [jira] [Commented] (HBASE-18840) Add functionality to refresh meta table at master startup
Date Wed, 20 Sep 2017 19:40:00 GMT

stack commented on HBASE-18840:
-------------------------------

bq. Are the region infos not updated on region merge/splits? 

Split and merges get a .regioninfo. The parent at least in the split case will still be around
so you'll need to figure which to favor reconstructing the meta.

You are dev'ing against branch-1 I take it?

Here is a hack from a million years ago to do similar HBASE-1867

> If a HBase cluster’s hbase:meta table is deleted or a cluster is started with a new
meta table, HBase needs the functionality to synchronize it’s metadata from Storage.
