Allen Wittenauer updated HADOOP-12857:
--------------------------------------
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.
* TOOL_PATH / HADOOP_TOOLS_PATH has been broken apart and replaced with
HADOOP_TOOLS_HOME, HADOOP_TOOLS_DIR and HADOOP_TOOLS_LIB_JARS_DIR to be
consistent with the rest of Hadoop.

> the number of tools grows. Let's rework this to be smarter.
