Subject [jira] [Created] (HADOOP-11393) Revert HADOOP_PREFIX, go back to HADOOP_HOME
Date Thu, 11 Dec 2014 18:23:16 GMT
Allen Wittenauer created HADOOP-11393:

             Summary: Revert HADOOP_PREFIX, go back to HADOOP_HOME
                 Key: HADOOP-11393
                 URL: https://issues.apache.org/jira/browse/HADOOP-11393
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Allen Wittenauer

Today, Windows and parts of the Hadoop source code still use HADOOP_HOME.  The switch to HADOOP_PREFIX
back in 0.21 or so didn't really accomplish what it was intended to do and only helped confuse
the situation.

_HOME is a much more standard suffix and is, in fact, used for everything in Hadoop except
for the top level project home.  I think it would be beneficial to use HADOOP_HOME in the
shell code as the Official(tm) variable, still honoring HADOOP_PREFIX if it is set.
