Error in deleting host in from a Kerberos enabled cluster.

Error in deleting host in from a Kerberos enabled cluster.

Explorer

Hi All,
I am getting this error while deleting a host from cluster.


Missing KDC administrator credentials.\nThe KDC administrator credentials must be set as a persisted or temporary credential resource.This may be done by issuing a POST to the /api/v1/clusters/:clusterName/credentials/kdc.admin.credential API entry point with the following payload:\n{\n \"Credential\" : {\n \"principal\" : \"(PRINCIPAL)\", \"key\" : \"(PASSWORD)\", \"type\" : \"(persisted|temporary)\"}\n }\n}"

In my cluster.json credential is:
"credentials": [{"alias": "kdc.admin.credential", "type": "TEMPORARY", "key": "test", "principal": "test/admin@TEST.COM"}]

Ambari Version: 2.7.3
