[jira] Commented: (HADOOP-1307) Documentation & classification of various configuration knobs

    [ https://issues.apache.org/jira/browse/HADOOP-1307?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12492770 ] 

Michael Bieniosek commented on HADOOP-1307:
-------------------------------------------

I'd rather see HADOOP-785 implemented first, since that is a logical separation, while this is developers guessing which configurable variables are more important.

> Given the ever-increasing number of configuration knobs for both dfs and mapred, it would be very useful in the long run to start and maintain up-to-date information (on the hadoop-wiki?) for these. While we are at it, it could be well worth the time to classify each as USER (must be overridden by user e.g. mapred.input/output.dir), BEGINNER, INTERMEDIATE, EXPERT (see HADOOP-1304) so as to clearly demarcate them.
> Thoughts?
