I don't think anyone has tried running Slider on MapR yet, so you are breaking new ground. I would not try to change CLASSPATH in slider-env.sh. Slider has a standalone lib directory, meaning that all of its required jars are in the lib dir (including hadoop jars). It might be the case that more jars are needed from the mapr lib directory. I would try copying all the jars from the mapr lib directory to the slider lib directory and see if that makes a difference. If it works, then you might be able to remove some of the jars.
