<property>
            <name>hadoop.proxyuser.root.hosts</name>
            <value>*</value>

    <property>
            <name>hadoop.proxyuser.root.groups</name>
            <value>*</value>
    </property>

After adding the property files into core-site.xml restart your hadoop and try. Even though if it not works format the namenode and start hadoop it will work.
