>             Project: Ambari
>          Issue Type: Bug
>          Components: ambari-web
>    Affects Versions: 2.4.0
>            Reporter: Antonenko Alexander
>            Assignee: Antonenko Alexander
>            Priority: Critical
>             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.
> Attached screenshot for reference.
> *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*
> Use the {{evaluate_when}} and (optionally) the {{additional_services}} _{{GET}} directives_
to have {{when}} Kerberos descriptor identitiy {{when}} clauses evaluated when requesting
Kerberos descriptors. 
> {noformat:title=Get composite Kerberos descriptor when enabling Kerberos}
> GET /api/v1/clusters/CLUSTER_NAME/kerberos_descriptors/COMPOSITE?evaluate_when=true
> {noformat}
> {noformat:title=Get composite Kerberos descriptor when adding services (HIVE, PIG, and
TEZ)}
> GET /api/v1/clusters/CLUSTER_NAME/kerberos_descriptors/COMPOSITE?evaluate_when=true&additional_services=HIVE,TEZ,PIG
> {noformat}
