Upgraded HBase addon to HBase 0.98.x and new Tuple APIs + fix of ExecutionEnvironment

Now it should be ok :+1: 
I the other tests, we deactivated logging. The reason is that otherwise, the logs overflow the screens when testing and exceed the limits of the log length on the build servers.

How about commenting the logger out (setting it to off) and adding a comment to the example, explaining how to activate the logging (by uncommenting the logger config)
