Thanks for the reply. That was all what was thinking about (port number, directory, bugs, etc.) regarding running the tetsts on the local node... So seems it's a good thing I stoped them.
If I stop my local datanode/region server, then bring down my network interface before I run the tests, I should be fine, right? I'm running the tests with my own user while hbase and hadoop are both running for a their own. I don't think there is a risk for the local test to fine and write on the local HBase/Hadoop files.
