HTTP 403: Yarn RM UI and History server UI are throwing java.lang.illegalargumentexception

[#1]

Hi All, 

Yarn RM UI and History server are throwing java.lang.illegalargumentexception when try to launch. 

Java version: 1.8.0_241

CDH: 6.2.1

Any Suggestions on how to over come this error.

@raghu9raghavend This error is coming due the the Kerberos Authentication is configured for your RM UI. You have 2 options:

1. Configure Browsers for Kerberos Authentication (Recommended)

2. Disable the Kerberos Authentication for Web UI from service configuration. CM > Yarn > Configuration > Enable Kerberos Authentication for HTTP Web-Consoles > Disable/uncheck this option and restart Yarn.
