Important environment variables
-------------------------------

The Pydoop setup looks in a number of default paths for what it
needs.  If necessary, you can override its behaviour or provide an
alternative path by exporting the environment variables below::

  JAVA_HOME, e.g., /opt/sun-jdk
  HADOOP_HOME, e.g., /opt/hadoop

Other relevant environment variables include::

  HADOOP_VERSION, e.g., 2.7.4 (override Hadoop's version string).
