Subject [jira] [Commented] (HADOOP-7624) Set things up for a top level hadoop-tools module
Date Tue, 13 Sep 2011 19:47:08 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7624?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13103930#comment-13103930

Doug Cutting commented on HADOOP-7624:

Allen, are all of these choices equally acceptable to you?  If not, what is your preferred

Some questions about each of these choices:

a. Are you proposing that things that are currently in various contrib directories move to
the hadoop-tools module created by this proposal?  If so, those sound like good follow-on
issues to file.

b. Where specifically in the current tree would you prefer we place the new distcp code (MAPREDUCE-2765)?
In hadoop-mapreduce-project/src/tools, beside the old distcp?

c. Will you propose and drive a new subproject?  Would the release cycle be separate from

d. Distcp is not currently in contrib.  Would you prefer that the new version be committed
in hadoop-mapreduce-project/src/contrib?

e. I think that's what's proposed here.  The 'rules and process' are not currently formalized.
 Rather it was agreed that we should be more cautious than before about accepting things and
that we be more aggressive about booting things when they're abandoned and/or stop passing
tests.  If you'd like to formalize this and build consensus around some rules and process
that'd be great.  Should we block the commit of MAPREDUCE-2765 on that?

> We need to get things up and running for a top level hadoop-tools module. DistCpV2 will
be the first resident of this new home. Things we need:
>  - The module itself and a top level pom with appropriate dependencies
>  - Integration with the patch builds for the new module
>  - Integration with the post-commit and nightly builds for the new module.
