Edward J. Yoon reopened HAMA-855:
---------------------------------
Re-open. In MiniBSPCluster, Master uses hard-coded 40000 port but we don't need
to specify the master port for unit test.
To avoid "already in use" execption, use the try-catch and then use the
available port. See HamaMessageManagerImp.startServer() method.
