> Key: AMBARI-17226
> URL: https://issues.apache.org/jira/browse/AMBARI-17226
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.4.0
> Reporter: Robert Levas
> Assignee: Robert Levas
> Fix For: 2.4.0
>
>
> 1. Deploy ambari cluster with YARN, HDFS, ZOOKEEPER and HBASE
> 2. enable security (AD)
> Expected: On ConfigureIdentities page hive.llap.zk.sm.principal and
> hive.llap.zk.sm.keytab.file
> should not be present if hive is not deployed on cluster.
> Actual: These 2 properties are showing under Ambari Principals panel even
> when Hive is not deployed on the cluster.
> *Cause*
> This is caused when identities that have {{when}} clauses are not filtered
> out if the when clause evaluates to {{false}} when the UI queries for the
> (composite) Kerberos Descriptor.
> *Solution*
> Add a {{GET}} directive to specify {{when}} clauses are to be evaluatated
> while building the Kerberos Descriptor using the following API call:
> {noformat}
> GET
> /api/v1/clusters/CLUSTER_NAME/kerberos_descriptors/COMPOSITE?evaluate_when=true
> {noformat}
