use http simple auth only for Web UIs and not for webhdfs

[anup ahire]

Hello Team,

I see that in hadoop 3.3.6, setting hadoop.http.authentication.type to
simple sets simple auth to webhdfs unlike previous verison like 3.1

I have a use case where I only want to skip spnego for web ui access and
not for webhdfs.

In HttpServer2.java, I see this

if (this.securityEnabled &&
    !this.conf.get(authFilterConfigurationPrefix + "type").
    equals(PseudoAuthenticationHandler.TYPE)) {
  server.initSpnego(conf, hostName, usernameConfKey, keytabConfKey);
}




I tried to modify this check and only check for securityEnabled like
previous Hadoop versions but it is not taking effect for webhdfs. Any idea
what may be needed more?

Thanks.
