Learned a bit - ACCUMULO - set classpath in accumulo-site.xml

Thank You for comment on my post -  Learned a bit - ACCUMULO. So, I modified "<name>general.classpaths</name>" in conf/accumulo-site.xml file. It works -:)

  <property>
    <name>general.classpaths</name>
    <!--

Warning!!! Your instance secret is still set to the default, this is not secure. We highly recommend you change it.


You can change the instance secret in accumulo by using:
   bin/accumulo org.apache.accumulo.server.util.ChangeSecret oldPassword newPassword.
You will also need to edit your secret in your configuration file by adding the property instance.secret to your conf/accumulo-site.xml. Without this accumulo will not operate correctly
