Sunil Govindan commented on YARN-8258:
--------------------------------------

Updating v4 patch with test case to check filter ordering as well.

{{httpServer.getWebAppContext().getServletHandler()}} was providing all 
filterHolding and filterMappings. UI2 is copying this context from default 
context. For Spnego, path spec has to be null to ensure that Spnego filter is 
coming after kerberos authentication filter. 

[~vinodkv] Could you  please help to check this.

> YARN webappcontext for UI2 should inherit all filters from default context
