Allen Wittenauer updated HADOOP-12857:
--------------------------------------
    Hadoop Flags: Incompatible change
    Release Note: 
* Turning on optional things from the tools directory can now be done via 
hadoop-env.sh without impacting the various user-facing CLASSPATH.
* The tools directory is no longer pulled in blindly for any utilities that 
pull it in.  

> Rework hadoop-tools-dist

> 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.
