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). -- Lars ----- Original Message ----- From: Kevin O'dell <[email protected]> To: "[email protected]" <[email protected]> Cc: Sent: Sunday, June 16, 2013 7:35 PM Subject: Re: Running HBase with different versions 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.
