Allen Wittenauer updated HADOOP-12857:
--------------------------------------
Release Note:
<!-- markdown -->
* Turning on optional things from the tools directory such as S3 support can
now be done in hadoop-env.sh with the HADOOP\_OPTIONAL\_TOOLS environment
variable without impacting the various user-facing CLASSPATH variables.
* 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.
