-------------------------------

    Status: Patch Available  (was: Open)

Attached a patch. Changes summary:
1. Moving signature file reading from AuthenticationFilterInitializer to 
AuthenticationFilter:

2. And in AuthenticationFilter, if SIGNATURE_SECRET is configured, then use it; 
otherwise if SIGNATURE_SECRET_FILE is configured, then use it; otherwise 
generate a secret as before.


> Allow AuthenticationFilter to respect signature secret file even without 
> AuthenticationFilterInitializer

> In Hadoop web console, by using AuthenticationFilterInitializer, it's allowed 
> to configure AuthenticationFilter for the required signature secret by 
> specifying signature.secret.file property. This improvement would also allow 
> this when AuthenticationFilterInitializer isn't used in situations like 
> webhdfs.
