Prabhu Joseph commented on HADOOP-16366:
----------------------------------------
[~eyang] Thanks for reviewing. It looks redundant but verified the logic is
correct. {{initializers}} variable has list of user configured initializers,
{{defaultInitializers}} will be the final list of initializers used.
If {{ProxyUserAuthenticationFilterInitializer}} is configured, then ignore both
{{AuthenticationFilterInitializer}} and
{{TimelineReaderAuthenticationFilterInitializer}}. Else,
{{TimelineReaderAuthenticationFilterInitializer}} will be used and ignore
{{AuthenticationFilterInitializer}}. And by default,
{{TimelineReaderWhitelistAuthorizationFilterInitializer}} will be used.
