Subject [jira] [Created] (MAPREDUCE-2472) Extra whitespace in mapred.child.java.opts breaks JVM initialization

Extra whitespace in mapred.child.java.opts breaks JVM initialization
--------------------------------------------------------------------

                 Key: MAPREDUCE-2472
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2472
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: task-controller
    Affects Versions: 0.20.2, 0.22.0
            Reporter: Todd Lipcon
             Fix For: 0.22.0


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.
