I am trying to kerberized cluster and all machines are adjoined with centrify.
I checked without kerberization all services are running fine but after kerberization of the cluster server logs showing following error:
Failed on local exception: java.io.IOException: Server asks us to fall back to SIMPLE auth, but this client is configured to only allow secure connections.; Host Details : local host is ; destination host is

@Ajit Sonawane Which version of ambari are you using ? What steps did you follow to kerberize the cluster?
I hope you have followed the steps as mentioned in https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.1/bk_security/content/configuring_amb_hdp_for.... If not please follow the doc to kerberize the cluster.
If you have followed the steps in the doc, then can you check /etc/security/keytabs/ and ensure that all the service keytabs are generated?

Issue is resoleved, when I added following property to core-site.xml
I think this issue occurs when you are dealing with cluster which was earlier kerberized and then dekerberized and vice-versa.
