Subject [jira] [Commented] (HADOOP-14665) Support # hash prefix comment lines in auth_to_local mapping rules
Date Fri, 10 Nov 2017 13:39:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14665?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16247502#comment-16247502

Hari Sekhon commented on HADOOP-14665:

Ok I didn't see that documented in the top few google hits and since it looks like a flat
unix config, hash comments were expected.

I still think supporting hash comments would be more intuitive as in management consoles all
the files which have free form configuration boxes are in unix file format and take hashes.

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
