HBase Error : zookeeper.znode.parent mismatch

hadoop, hbase

Solution

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.

Problem

i am trying to learn Hadoop and i'v reached HBase section in Hadoop Definitive Guide. i tried to start HBase and got error. Could someone give me step-by-step guide? ``` opel@ubuntu:~$ zkServer.sh start JMX enabled by default Using config: /home/opel/zookeeper-3.4.6/bin/../conf/zoo.cfg Starting zookeeper ...
