Subject [jira] [Updated] (HADOOP-12857) Rework hadoop-tools
Date Thu, 10 Mar 2016 19:21:40 GMT

     [ 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 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.

> 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.
