Subject [jira] [Commented] (YARN-673) Remove yarn-default.xml
Date Mon, 13 May 2013 20:31:16 GMT

    [ https://issues.apache.org/jira/browse/YARN-673?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13656343#comment-13656343

Siddharth Seth commented on YARN-673:
-------------------------------------

The documentation will be part of the source tree, so keeping it up to date should not be
any tougher. Grepping through *-default.xml is really only for developers - and that should
be possible on the documentation as well. Since these files sit insider jars - I don't see
how they serve as documentation iac.

> The default configuration files serve 2 purposes
> 1. Documenting available config parameters, and their default values.
> 2. Specifying default values for these parameters.
> An xml file hidden inside a jar is not necessarily the best way to document parameters.
This could be moved into the documentation itself.
> Default values already exist in code for most parameters. There's no need to specify
them in two places. We need to make sure defaults exist for all parameters before attempting
this.
> Having default configuration files just bloats job conf files; over 450 parameters, out
of which <20 are likely job specific params. JobConf files end up being rather big, and
the memory footprint of the conf object is large (>300KB last I checked).
