The backup function is called from a couple of places and it is not a recent addition based on git history. You can manually disable it by commenting out the copy call in the python code at: /usr/lib/python2.6/site-packages/ambari_server/serverConfiguration.py def backup_file_in_temp(filePath):

amabri.properties file does not store any passwords. Is any other data classified as sensitive on your end?

Actually, Grafana allow dashboard import. You might be able to just get the dashboard definition from Ambari source and import into you existing Grafana. Here is link to trunk dashboard locations: https://github.com/apache/ambari/tree/trunk/ambari-server/src/main/resources/common-services/AMBARI_METRICS/0.1.0/package/files/grafana-dashboards/HDP Import is pretty straightforward: http://docs.grafana.org/reference/export_import/

Make sure to use Ambari-2.2.2. A related issue was fixed in 2.2.2 https://issues.apache.org/jira/browse/AMBARI-15774

@Angel Kafazov Were you able to verify the AMS keytabs work? Most of the config changes performed above were not needed, example changes to zookeeper and znode settings : For distributed mode only config changes needed are these: https://docs.hortonworks.com/HDPDocuments/Ambari-2.1.1.0/bk_ambari_reference_guide/content/_configuring_ambari_metrics_for_distributed_mode.html When you enable security through Ambari the keytabs and principals are generated by Ambari and applied to AMS configs. Before looking into ambari-metrics-collector.log or ambari-metrics-monitor.out, the ams-hbase daemon should be up and running fine, if not the connection timeouts are of no help since these are expected. Based on the hbase logs posted the HBase daemon tried to login and failed, so we need to figure out why it did fail. Note: If the collector was moved older keytabs would become invalid because hostname changed and would have to be re-generated. Example of keytab commands: http://dev.hortonworks.com.s3.amazonaws.com/HDPDocuments/HDP1/HDP-1.2.0/bk_installing_manually_book/content/rpm-chap14-1-4.html

Both Master and Regions server logs indicate unable to login to Kerberos. Login failure for amshbasemaster/m2.DOMAIN@DOMAIN from keytab /etc/security/keytabs/ams-hbase.regionserver.keytab: javax.security.auth.login.LoginException: Unable to obtain password from user Can you check if you can manually login with the ams keytabs under /etc/security/keytabs/ams*.keytab Example: kinit -kt /etc/security/keytabs/ams-hbase.regionserver.keytab amshbasemaster/m2.DOMAIN@DOMAIN

@Geoffrey Shelton Okot The document suggests setting the zookeeper.znode.parent to the same value as HBase service which is somewhat incorrect for versions > 2.1.2.1. Prior to 2.2, the value was not set so it defaulted to /hbase, this was ok because AMS started its own ZK. Post 2.2, AMS talks to cluster ZK and thereby the znode is set to /ams-hbase-(unsecure/secure). Logs would indicate whether TGT was acquired correctly and if the problem is something totally different.
