Configure hbase in pseudo distributed mode

I am trying to configure hbase in pseudo distributed mode. I have tried many tutorials but every time i get this error in my log

I have tried following solutions

My hbase-site.xml is this

<configuration>
      <property>
           <name>hbase.rootdir</name>
            <value>file:///home/freeswitch/TryNutch/hbase</value>
       </property>
       <property>
          <name>hbase.cluster.distributed</name>
          <value>true</value>
       </property>
      <property>
           <name>hbase.zookeeper.property.dataDir</name>
           <value>/home/freeswitch/TryNutch/zookeeper</value>
       </property>
</configuration>

Thank for reading this post.
your help is much needed.

First things first, replace file:///home/freeswitch/TryNutch/hbase with proper value if you intend to run HBase in distributed mode. I can see hbase.cluster.distributed set to true. Point it to your NameNode address. Something like hdfs://localhost:9000/hbase.

Also, add the following two properties in your hbase-site.xml file :

<property>
        <name>hbase.zookeeper.quorum</name>
        <value>localhost</value>
</property>
<property>
        <name>hbase.zookeeper.property.clientPort</name>
        <value>2181</value>
</property>

Make sure your NameNode is running fine, and restart HBase daemons. If you still face any problem try following this link. I have tried to explain the procedure in detail. Let me know if you still face any issue.
