upgrade from hbase 0.90.1 to 0.90.2

Hi
   We running on hbase 0.90.1 and want to upgrade to 0.90.2.
What is the process to do it , I mean is it enough to change the jar or it
requires configuration files changes.
Please advice
Oleg.

Its a point release so stop the cluster, replace your hbase directory
with the new, and restart.  Otherwise, rolling restart your cluster.
There is some discussion on how here:
http://hbase.apache.org/book.html#decommission (Scripts added in
0.90.2 facilitate rolling restarts).
