Re: Running HBase with different versions
Yep. At least the 0.94.x release are carefully designed to have 100% client server compatibility between minor versions.

That said, we sometimes add new features and/or improvements that are only available with the new clients, so an eventual upgrade of the client is recommended (but by no means required).

I agree with JM on this one, minor version should be fine unless there is a
major known issue.  On the other hand, if it is within control you should
always try to match client with server versions.
