Subject Re: Local RegionServer vs JUnit?

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.
