Allen Wittenauer commented on HADOOP-12857:
-------------------------------------------
-00:
tl;dr: HADOOP_TOOLS_PATH is no longer used in the codebase
* removed toolspath from haadmin because I can't see what it needs from there
and mvn dependencies don't list anything either
* added various HADOOP_TOOLS_* vars to locate content, similar to what is
present for the other parts of Hadoop
* added those entries to the various envvars subcommands
* added the necessary hooks to build profiles and built-ins
* changed all of the built-ins to use the specific hooks for them at runtime
* added generic *_entry handlers to deal with comma delimited options
* added ability to turn on built-in optional components from hadoop-env.sh
without doing anything crazy
* added and modified quite a few shell unit tests to test all this code
* added commons-httpclient back to openstack so I could move forward (see
HADOOP-12868)
Todo:
* need to update the docs for S3, etc, to tell how to turn them on now

> 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.
