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