      Description

      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.
