Subject [jira] [Commented] (MAPREDUCE-279) Map-Reduce 2.0
Date Tue, 16 Aug 2011 23:33:31 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-279?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13086039#comment-13086039

Alejandro Abdelnur commented on MAPREDUCE-279:
----------------------------------------------

I've just applied the patch following instructions and it compiles fine.

Yesterday I've opened a JIRA with things to improve, MAPREDUCE-2842.

IMO, most of those can be done incrementally after this patch goes in.

What I think it should be done as part of this patch (MAPREDUCE-279) is the artifact/maven-module-dir
names.

All artifact names should be prefixed with 'hadoop-' (the JARs get the artifact names and
it will be easier to troubleshoot, identify the JARS).

In addition, the maven-module-dir should be the same to make it easier to developers to find
their way around.

The reason for proposing doing this as part of this patch is to avoid doing 2 huge moves of
files in SVN.

(HDFS-2096 is aligned to this naming already)

Thanks
