HBase Error : zookeeper.znode.parent mismatch

I had the same problem. For me the solution was to add the following property to the hbase-site.xml (for me it can be found under /usr/lib/hbase/conf directory):

<configuration>
        <property>
                <name>zookeeper.znode.parent</name>
                <value>/hbase-unsecure</value>
        </property>
</configuration>

But this is only for the standalone mode. I still have no idea how to solve this problem when using external ZooKeeper.

there wont be any problem with the configurations if you are using the Cloudera Manager VM.

The problem is HMaster is not up. To resolve it, go to Cloudera Manager and restart the HBase services. it will resolve the issue.
