<para>A rolling upgrade is the process by which you update the servers
in your cluster a server at a time. Coarsely, you do a graceful stop of the server
update the software and then restart. You do this for each server in the cluster.
Usually you upgrade the Master first and then the regionservers.
See <xlink href="rolling" /> for tools that can help use the rolling upgrade process:
e.g. install the new software and configs and then do a rolling restart to come up on it.</para>
