Lars Francke updated HBASE-10815:
---------------------------------
Description:
In HBASE-10569, two things could affect the rolling-upgrade from a 0.96+
release:
* Master doesn't have its own info server anymore. It shares the same info
server with the regionserver. We can have a setting so that we can start two
info servers, one for the master on the original port, and one for the
regionserver.
* Backup master is a regionserver now. So it could hold regions. This could
affect some deployment. We can have a setting so that we can prevent backup
master from serving any region.
