Subject Re: Unable to Start Ambari Metrics Collector

In the RS log:

org.apache.zookeeper.KeeperException$NoAuthException: KeeperErrorCode = NoAuth for /ams-hbase-secure/running

1. 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/<>
and amshbasemaster/<>

Subject: Unable to Start Ambari Metrics Collector


I have changed my  Ambari Metrics from embedded to distributed environment on my secure cluster.

After I have tried to start the Ambari Metrics Collector, unable to start the service. I have
tried to debug the issue, but i couldn't able to resolve the issue.

I have verified all the keytab files, all are able to initiate. and I saw the log in "ambari-metrics-collector.log"
