The relevant environment to test for this change is singlenode-kerberos-hdfs-impersonation. These product tests are run via docker, and relevant Kerberos docker image is here: https://github.com/Teradata/docker-images/blob/master/teradatalabs/cdh5-hive-kerberized/Dockerfile. In order to test this change, we'll have to change the docker image to use _HOST when creating the principals."}}
