INFO: Caused by: org.apache.hadoop.security.authentication.client.AuthenticationException: Authentication failed, URL: http://rangerkms.example.com:9292/kms/v1/?op=GETDELEGATIONTOKEN&doAs=w20524%4542test.tt&renewer=r m%2Fsktudv01hdp02.test.tt%40CCTA.DK&user.name=livy, status: 403, message: Forbidden

Root Cause: Missing proxy users for livy in kms. The solution is to add the following into Ambari Custom kms-site

hadoop.kms.proxyuser.livy.users=* 
hadoop.kms.proxyuser.livy.hosts=* 
hadoop.kms.proxyuser.livy.groups=*
