To get the number of vcores and memory used for a particular queue in the cluster You can get this information in the cluster utilization report, please go through the below doc for more information: https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/admin_cluster_util_report.html Also, if you want to see the resources used for each application, please go through the below KB article: https://my.cloudera.com/knowledge/How-to-calculate-memory-and-v-core-utilization-for-each-of-the?id=271149 another option is Using   yarn application -status   command, you can get the   Aggregate Resource Allocation   for an application. For e.g.    yarn application -status application_ID   (for one of completed applications), one of the rows returned is: Aggregate Resource Allocation : 46641 MB-seconds, 37 vcore-seconds This gives an aggregate memory and CPU allocations in seconds. https://my.cloudera.com/knowledge/How-to-calculate-memory-and-v-core-utilization-for-each-of-the?id=271149 ...

To invoke kerberos related operations via Ambari APIs requires, we store the KDC credentials to the Ambari's credential store. For more information on the same please refer to: https://community.cloudera.com/t5/Community-Articles/Adding-KDC-Administrator-Credentials-to-the-Ambari/ta-p/246591   1. To set up Ambari's credential store, the following command must be invoked from the Ambari server host's command line: # ambari-server setup-security Then choose option [2] Encrypt passwords stored in ambari.properties file.   2. Review the changes. Once this is complete, the Ambari credential store will be located at /var/lib/ambari-server/keys/credentials.jceks.   3. Restart ambari server.   4. Now we should be able to store the KDC credentials to the ambari credentials store.   # curl -u admin:admin -H 'X-Requested-By: ambari' -X POST -d '{ 'Credential' : {'principal' : 'admin/admin@EXAMPLE.COM ', 'key' : 'admin','type' : 'persisted'}}' http://example.com:8080/api/v1/clusters/kerberos_ambari/credentials/kdc.admin.credential   5. After this we should be able to run the Kerberos API calls like following:   Regenerate for all   curl -u admin:admin -H 'X-Requested-By: ambari' -X PUT -d '{'Clusters':{'security_type':'KERBEROS'}}' http://example.com:8080/api/v1/clusters/kerberos_ambari?regenerate_keytabs=all   (OR) Below is for missing once.   curl -u admin:admin -H 'X-Requested-By: ambari' -X PUT -d '{'Clusters':{'security_type':'KERBEROS'}}' http://example.com:8080/api/v1/clusters/kerberos_ambari?regenerate_keytabs=missing ...
