> 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.
