I think that you should follow the CDH4 Beta 2 docs, specifically the
know issues for this version:
https://ccp.cloudera.com/display/CDH4B2/Known+Issues+and+Work+Arounds+in+CDH4
Then, you should see the HBase installation and upgrading on this version:
https://ccp.cloudera.com/display/CDH4B2/HBase+Installation#HBaseInstallation-InstallingHBase
Another thing that you keep in mind is that with HBase 0.92.1, you
should restart your cluster because
the wire protocol changed from 0.90 to 0.92, so, the rolling restarts do
not work here.
Best wishes

Hi,
I have used CDH3U2 for almost a year now. Since it is a quite old
distribution, there are certain glitches that keep bothering me.
So I was considering upgrading to Hadoop 1.0.3 and Hbase 0.92.1.
My concern is that, if it is okay to just install the new packages and set
the configurations the same as before?
Or do I need to download all the files on HDFS to local hard drive and
upload them again once the new packages are installed? (that would be a
horrible job to do though)
Any advice will be helpful.
Thanks.
