Subject [jira] Commented: (MAPREDUCE-1404) Hadoop M/R Docs - delete 1 doc file that does not belong under M/R
Date Sat, 23 Jan 2010 08:52:18 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1404?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12804048#action_12804048

Hemanth Yamijala commented on MAPREDUCE-1404:

Is this the right direction ? cluster_setup.xml contains elaborate steps to properly configure
an HDFS / mapreduce cluster. Shouldn't the mapreduce parts be available under the mapreduce
project, in the spirit of project split ? Indeed, given that 'common' is just a set of utility
libraries, the real crux of cluster_setup will be in the HDFS and mapreduce subprojects -
like how to setup an HDFS cluster and how to setup a mapreduce cluster. 

>From a developer / committer perspective, any patch of HDFS or mapreduce that introduces
a change that we think influences cluster setup of the respective component will then generate
two JIRAs - one for the code change and another for the documentation. The synchronization
of these patches will become an overhead for committers, IMHO.

If we do decide to go with just one version under common, we should make sure to merge changes
done to the mapreduce parts of cluster_setup.xml with common's version. I remember having
reviewed changes to cluster_setup.xml (involving mapreduce parts) and committing them here.
But I'd be more interested to know if we can come up with a different organization.
