-------------------------------------
Summary: Confusing output when running "hadoop version" from one
hadoop installation when HADOOP_HOME points to another
Key: MAPREDUCE-4659
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4659
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: client
Affects Versions: 2.0.1-alpha
Reporter: Sandy Ryza
Hadoop version X is downloaded to ~/hadoop-x, and Hadoop version Y is
downloaded to ~/hadoop-y. HADOOP_HOME is set to hadoop-x. A user running
hadoop-y/bin/hadoop might expect to be running the hadoop-y jars, but, because
of HADOOP_HOME, will actually be running hadoop-x jars.
"hadoop version" could help clear this up a little by reporting the current
HADOOP_HOME.
