[jira] [Comment Edited] (HADOOP-14665) Support # hash prefix
comment lines in auth_to_local mapping rules
[ https://issues.apache.org/jira/browse/HADOOP-14665?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16247502#comment-16247502 ]

Ok I didn't see that documented in the top few google hits, maybe it's just not widely known, 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 config file format and use hash comments.

> Key: HADOOP-14665
> URL: https://issues.apache.org/jira/browse/HADOOP-14665
> Project: Hadoop Common
> Issue Type: Improvement
> Affects Versions: 2.7.3
> Environment: HDP 2.6.0 + Kerberos
> Reporter: Hari Sekhon
>
> 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.
