When creating taskjvm.sh, we split mapred.child.java.opts on " " and then create a quoted argument for each of those results. So, if you have an extra space anywhere in this configuration, you get an argument '' in the child command line, which the JVM interprets as an empty class name. This results in a ClassNotFoundException and the task cannot run.
