Subject [jira] Updated: (HADOOP-1307) Classification of various configuration knobs
Date Mon, 30 Apr 2007 20:16:15 GMT

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

Arun C Murthy updated HADOOP-1307:
----------------------------------

    Description: 
Given the ever-increasing number of configuration knobs for both dfs and mapred, it would
be very useful to classify each as EXPERT or not so as to clearly demarcate them. 

Thoughts?

  was:
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?

        Summary: Classification of various configuration knobs  (was: Documentation &
classification of various configuration knobs)

Updated based on feedback by Doug/Michael, lets just shoot for expert/non-expert classification,
keeping in mind HADOOP-785.
