/**
* Starts an on-demand mini cluster that requires no set up.
*
* <p>It can be useful if you don't want to restart the cluster between each run of test and don't
* want to set up a real cluster.
*
* <p>CLASSPATH needs to contain: pig.jar and piggybank.jar
* <pre>
* export CLASSPATH=/path/pig.jar:/path/piggybank.jar
* java org.apache.pig.pigunit.MiniClusterRunner
* </pre>
*
* <p>Possible improvements
* <ul>
* <li>add a main in MiniCluster</li>
* <li>make MiniCluster configurable (number of maps...)</li>
* <li>make MiniCluster use a default properties for chosing the hadoop conf dir
* (e.g. minicluster.conf.dir) instead of always using
* System.getProperty("user.home"), "pigtest/conf/"</li>
* <li>use CLI option</li>
* <li>make a shell wrapper</li>
* </ul>
