[jira] [Commented] (HADOOP-14665) Support # hash prefix comment lines in auth_to_local mapping rules

["Andras Bokor (JIRA)" <ji...@apache.org>]

Andras Bokor commented on HADOOP-14665:
---------------------------------------

I does not seem like a missing feature. You can use standard xml comments, do not need to implement an own comment logic.

> Request to add support for # hash prefixed comment lines in Hadoop's auth_to_local mappings rules so I can comment what rules I've added and why inline to the rules like with code (useful when supporting multi-directory mappings).
> It should be fairly easy to implement, just string strip all lines from # to end, trim whitespace and then exclude all blank / whitespace lines, I do this in tools I write all the time.
