Found two issues:
1. HttpFSAuthenticationFilter#getConfiguration doesn't set the AUTH_TYPE property to the name of the corresponding auth handler class;
2. We need to set the TOKEN_KIND in HttpFSAuthenticationFilter , I choose to do it in HttpFSAuthenticationFilter#getConfiguration.
Submitted patch 001 to address them, and verified that it works in a real cluster.
Hi Alejandro Abdelnur and Arun Suresh,
Many thanks for the help when I investigated this issue. Would you please taking a look at the patch I just submitted? Thanks!
