When running map reduce tasks in Hadoop I run into classpath issues. Contrary to previous posts, my problem is not that I am missing classes on the Task's class path (we have a perfect solution for that) but rather find too many (e.g. ECJ classes or jetty).
The libs in HADOOP_HOME/lib seem to contain everything needed to run anything in Hadoop which is, I assume, much more than is needed to run a map reduce task. Is there a doable way of taking just those needed for map reduce jobs and have the class path for m/r tasks point to just those? I.e.: What would that set of libs comprise and where to specify the class path for m/r tasks? Thanks, Henning
