      I ran it using a local, recieved NullPointerException. my configurations are as below:

      <configuration>
        <property>
          <name>bsp.master.address</name>
          <value>test.server.org:40000</value>
          <description></description>
        </property>
      
      <property>
        <name>fs.default.name</name>
        <value>hdfs://test.server.org:9000/</value>
        <description></description>
      </property>
      
      
      <property>
          <name>hama.zookeeper.quorum</name>
          <value>localhost</value>
          <description>Comma separated list of servers in the ZooKeeper Quorum.
          For example, "host1.mydomain.com,host2.mydomain.com,host3.mydomain.com".
          By default this is set to localhost for local and pseudo-distributed modes
          of operation. For a fully-distributed setup, this should be set to a full
          list of ZooKeeper quorum servers. If HBASE_MANAGES_ZK is set in hbase-env.sh
          this is the list of servers which we will start/stop ZooKeeper on.
          </description>
        </property>
      
      </configuration>
