Apache Oozie UI: getting HTTP Status 401 - org.apache.hadoop.security.authentication.util.SignerException: Invalid signed text:

[#1]

getting the following error on Oozie UI, cluster is kerborized, HDP 2.5.3, Ambari 2.5 (dev build):

1. HTTP Status401- org.apache.hadoop.security.authentication.util.SignerException:Invalidsigned text:

[#2 · Accepted solution]

I got rid off SPNEGO on this cluster and set

oozie.authentication.type=simple

as I'm accessing from Mac, I don't need SPNEGO. I'm able to access Oozie UI now.
