     [ https://issues.apache.org/jira/browse/HADOOP-12857?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.

> 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.
