Hi Exception,
For starters the logs say you are trying the wrong ZooKeeper node to
get the HBase details (localhost) and you config has:
<property>
<name>hbase.zookeeper.quorum</name>
<value>dev32</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>localhost</value>
</property>
<property>
You are declaring it twice and the last one wins. Remove the second definition.
