Answer / Santosh Kumar Kanhiya
Besides the jps command, you can use web interfaces provided by Hadoop to check the Namenode status. You can access the Namenode's web UI at http://[namenode-ip]:50070/dfshealth.html or you can use Hadoop command: hadoop dfsadmin -report to get a detailed report about the cluster health.
