      Description

      Hi, I noticed recently folks are really focusing on documentation. (Kudos to +[~ajisakaa], +Brahma Reddy Battula, +Masatake Iwasaki, +Daisuke Kobayashi, +John Zhuge and more).

      I've been following Hadoop documentation to set up web UI authentication, but it seems to be contradicting between docs, for example, for web UI Kerberos keytab settings:

      • in Hadoop in Secure Mode (SecureMode.md), HDFS daemons have distinct web UI authentication configs, for example, for name node that's dfs.web.authentication.kerberos.keytab,
      • but in Authentication for Hadoop HTTP web-consoles (HttpAuthentication.md), it mentions a Hadoop-wide config: hadoop.http.authentication.kerberos.keytab;
      • finally, in Hadoop Auth, Java HTTP SPNEGO - Server Side Configuration(Configuration.md), it says{{[PREFIX.]kerberos.principal}} should be used.

      They all seem to mean one thing, but different configuration names. So it's a bit of confusing, or even contradicting to each other. Can we improve it?
