All you really need is a 0.92.2 client that runs 0.92.2, no need to
restart anything.

Yes... if you do have multiple assignments it could make the rolling
restart harder.

It's a different build profile that includes code with dependencies on
the security-related classes in Hadoop, which are not present in
versions like 0.20, 0.20-append, 0.21, 0.22, etc

0.96.0 will be the first HBase release that requires at least Hadoop
1.0, which means that we won't need two tarballs.
