Hi, I have inherited some Hadoop 3.1.1 clusters. There is a configured connection between SAP BO and Hadoop using Knox 1.0.0 as the Proxy for authentication. The problem that I have is that I don´t count with user to authenticate to Knox, and I need to edit the gateway. Is there a way to recover the admin password? Thanks for your support.

Hi Jim, thanks for your prompt answer. Here my answers: 1) what do the logs say? nothing relevant, just the illegal argument exception, for example: 2022-09-08 16:15:42,386 WARN server.AuthenticationFilter (AuthenticationFilter.java:doFilter(608)) - Authentication exception: java.lang.IllegalArgumentException 2)Thanks for the information provided, but I am not able to identify if the config is ok or not. One important thing perhaps to mention is that the Yarn Server is in one domain (let´s call it A) but the user authentication is done to a different domain (let´s call it B). For what I see in the headers, the server side and the client side are making reference of domain A, which makes sense, but I can´t identify in which moment the illegal argument comes up 3) the domain controllers were deprecated, and we had to reconfigure the Kerberos information by the servers in the Cluster plus run the Ambari Ldap Setup to make reference to the new DC. We did not modify anything regarding Yarn, Oozie or the other services. Thanks for your help, Jesus

Hello community, After a recent Domain Controler update, our fully kerberized Cloudera cluster 3.1.1 does not allow us to login the web interfaces of Oozie and YARN (the underneath services are working fine, apps are up and running) When authenticating, we receive in the browser the following message: HTTP 403 - Authentication exception: java.lang.IllegalArgumentException. We have tried with different browsers, and configured them to work with the Kerberos authentication as explained in other threads. It is important to mention, that the authentication worked fine before the Domain Controller update. Any ideas on how to solve this? thanks for your support.
