Subject [jira] [Commented] (HADOOP-12857) Rework hadoop-tools
Date Thu, 17 Mar 2016 13:00:36 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12857?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15199458#comment-15199458

Allen Wittenauer commented on HADOOP-12857:

bq. I wish there was a way to dynamically add subcommands to hadoop, mapred, etc, but the
code just isn't quite there yet. We can do usage now, but not actually execution.

I know how to do this now in a very clean way that would even allow 3rd parties to add subcommands
to the shell commands.  It is definitely complimentary to this patch, but I'll wait for this
one to get committed before taking that on since it's a much bigger patch.

> As hadoop-tools grows bigger and bigger, it's becoming evident that having a single directory
that gets sucked in is starting to become a big burden as the number of tools grows.  Let's
rework this to be smarter.
