@Vishal Gupta Unfortunately the only proper method is going through the Ambari UI. Make sure you have the KDC credential and ensure the KDc server is accessible and running. Log in to Ambari Web and Browse to Admin > Kerberos. Click Disable Kerberos to launch the wizard. Complete the wizard. Restart all the HDP components Official doc Hope that helps ... View more

@Anurag Mishra First check the value of `zookeeper.znode.parent` in HBase. Set it to the same value in Ambari, Kill all the metrics processes running on the node. `ps -ef | grep metrics` and kill all of them as they were caching the `/hbase` value. Watch the ambari metrics collector logs ( /var/log/ambari-metrics-collector/ambari-metrics-collector.log) while you do the below steps Steps: 0. tail -f /var/log/ambari-metrics-collector/ambari-metrics-collector.log 1. Stop Ambari 2. Kill all the metrics processes 3. curl --user admin:admin -i -H "X-Requested-By: ambari" -X DELETE http://`hostname -f`:8080/api/v1/clusters/CLUSTERNAME/services/AMBARI_METRICS => Make sure you replace CLUSTERNAME with your cluster name 4. Refresh Ambari UI 5. Add Service 6. Select Ambari Metrics 7. In the configuration screen, make sure to set the value of `zookeeper.znode.parent` to what is configured in the HBase service. By default in Ambari Metrics it is set to empty value. 8. Deploy In embedded mode then hbase.cluster.distributed should be false, and hbase.rootdir set to a local directory using the "file://" scheme. ... View more
