Subject [jira] [Created] (MAPREDUCE-3839) Improve the single node setup docs for MR
Date Wed, 08 Feb 2012 14:19:59 GMT
Improve the single node setup docs for MR
-----------------------------------------

                 Key: MAPREDUCE-3839
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3839
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: documentation
    Affects Versions: 0.23.1
            Reporter: Harsh J
            Priority: Trivial


I'm gonna be recording all nits I can about the page at http://hadoop.apache.org/common/docs/r0.23.0/hadoop-yarn/hadoop-yarn-site/SingleCluster.html
here:

* The section at http://hadoop.apache.org/common/docs/r0.23.0/hadoop-yarn/hadoop-yarn-site/SingleCluster.html#Mapreduce_Tarball
is suitable to developers, not users. We should instead just point to releases page for tarball.
* On http://hadoop.apache.org/common/docs/r0.23.0/hadoop-yarn/hadoop-yarn-site/SingleCluster.html#Setting_up_the_environment
since the tarball structure is definite, we could do better to either point to a link to configure
HDFS and Common or provide instructions ourselves. Same applies to path the MR envs ought
to be set to -- none of these are mentioned.
* Under http://hadoop.apache.org/common/docs/r0.23.0/hadoop-yarn/hadoop-yarn-site/SingleCluster.html#Setting_up_Configuration.
one of the "Add the following configs" text is defined as a heading, while other isn't.
* The "Create Symlinks" and "Running daemons" sections do not appear in the index on top.
* Remove the "Good luck." at the end -- Users shouldn't need luck to setup good stuff :)

OT comment: The "Create Symlinks" part is curious. That we need symlinks to run MR looks very
wrong to me.
