Edward J. Yoon commented on HAMA-855:
-------------------------------------
1. You should attach the patch file instead of using comment.
2. getInt() method receives two arguments. 2nd is for when "bsp.master.port" is
not set.
int defaultPort = conf.getInt("bsp.master.port", 40000);
>> In MiniBSPCluster, Master uses hard-coded 40000 port but we don't need to
>> specify the master port for unit test.
In my opinion, BSPMaster's port should be able to specified by user and throw
the exception if it's already in use. As I mentioned above, Please change the
MiniBSPCluster.
