@Yukti Agrawal Are you facing this issue with some specific browser like "Google
Chrome" ? Or have you tried with other browsers as well? Sometimes this
kind of issue might happen due to browser setting as well like: http://stackoverflow.com/questions/25277457/google-chrome-redirecting-localhost-to-https

@Yukti Agrawal I will check why is it happening .. at my lab with similar setup. In the mean time as a quick workaround you might want to setup HTTPs for Grafana which is quite easy. https://docs.hortonworks.com/HDPDocuments/Ambari-2.4.2.0/bk_ambari-user-guide/content/setup_https_for_grafana.html

@Yukti Agrawal - By any chance have you added "https" instead of "http" in your "Advanced ams-grafana-ini" for the "protocol" field?

@Nigel Jones Can you please share the screenshot of the screen shot where you were expecting to see Ranger?
I am not able to find the link that you mentioned to navigate "started->select version" --> "choose services" But i see it here:
Ambari UI --> "Add Service" (button) --> "Choose Services" --> "Ranger" .

"Not Secure" usually means that the certificate identity cannot be verified. Usually this happens when you use "Self Signed" Certificates (instead of using a CA-signed certificate).
But still if you want then you can disable that warning though like: For Chrome: https://developers.google.com/web/updates/2016/10/avoid-not-secure-warn
FireFox: https://support.mozilla.org/t5/Fix-slowness-crashing-error/What-does-quot-Your-connection-is-not-secure-quot-mean/ta-p/30354

Regarding your query "You are able to open NameNode UI at port 50470 and DataNode UI at 50475. But connection is still showing as insecure." >>> Can you please let us know where exactly are you checking that the connection is unsecure? If it is a lab environment then we can enable the HADOOP_OPTS to have the Debug option "-Djavax.net.debug=ssl" enabled. that will show us more detailed information about the SSL communication .. if it is happening correctly or not? . Regarding Enabling "Ranger" SSL" you might want to refer to: https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.4.0/bk_Security_Guide/content/configure_non_ambari_ranger_ssl_self_signed_cert_admin.html

@Sachin Ambardekar On the agent host do the following first? Then try again: yum remove ambari-agent -y
rm -rf /etc/ambari-agent/*
rm -rf /var/lib/ambari-agent/*
rm -f /usr/sbin/ambari*
rm -f /usr/lib/python2.6/site-packages/ambari_commons
rm -rf /usr/lib/python2.6/site-packages/resource_management
rm -rf /usr/lib/python2.6/site-packages/ambari_jinja2 And then try installing agent from ambari UI. Or manually install the agent as following: wget -nv http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.4.2.0/ambari.repo -O /etc/yum.repos.d/ambari.repo
yum install ambari-agent -y .

@rahul gulati Can
you please double check if you have followed the steps as mentioned in
the article in order to enable SSL for HDFS components ? https://community.hortonworks.com/articles/52875/enable-https-for-hdfs.html AND https://community.hortonworks.com/articles/52876/enable-https-for-yarn-and-mapreduce2.html Also are you able to run service checks properly from ambari UI for HDFS?

@Sachin Ambardekar Where do you see that error? Can you please share the screenshot of the error if it is is in the UI? Also do you see more detailed error inside the "/var/log/ambari-server/ambari-server.log"? If the ambari-agent is already running then on the agent host it will be good to look at "//var/log/ambari-server/ambari-agent.log"
