Hi, I have created required keytabs for AMS. ams.collector.keytab ams-hbase.master.keytab ams-hbase.regionserver.keytab ams-zk.service.keytab All keytabs are able to "kinit" without any issue. Not able to trace out the issue. Please help us to trace this issue.

Do you have ams keytabs at /etc/security/keytabs ? If no, create and put keytabs to /etc/security/keytabs (see principal names and keytabs paths at ams-hbase-security-site config) The easiest way is to disable security for the cluster and enable it again, Security Wizard will create all the required keytabs for you. 2. Check with kinit if you can get a ticket from kerberos server for amshbase/[email protected]<mailto:[email protected]> and amshbasemaster/[email protected]<mailto:[email protected]> ________________________________ From: Shaik M <[email protected]<mailto:[email protected]>> Sent: Wednesday, November 11, 2015 12:15 PM To: [email protected]<mailto:[email protected]> Subject: Unable to Start Ambari Metrics Collector Hi, I have changed my Ambari Metrics from embedded to distributed environment on my secure cluster.
