Node /hbase is not in ZooKeeper

Question

When running PredictionIO on a local single node Hadoop (HortonWorks) I get the following error:

 Storage Backend Connections

  Verifying Event Data Backend
  ERROR client.HConnectionManager$HConnectionImplementation - The node /hbase is not in ZooKeeper. It should have been written by the master. Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.

How should I configure HBase + Zookeepr on a local Hadoop installation?

Have you start hbase-master before hbase-regionserver? It seems the master isn't started or have some errors. — ALSimon, Dec 16 '14 at 19:01
I start *all* services from HortonWorks web interface. Is it possible that it starts them in the wrong order? — zork, Dec 16 '14 at 19:22

At Hbase folder /conf/hbase-site.xml, config or add:

<property>
  <name>hbase.zookeeper.property.dataDir</name>
  <value>YOUR ZOOKEEPER FOLDER</value>
</property>

For example:

<property>
  <name>hbase.zookeeper.property.dataDir</name>
  <value>/home/myname/zookeeper-3.4.6</value>
</property>
