      Description

      On Amazon EC2, If I set mapred.child.java.opts to "-Xmx512m". Job execution fails saying that "Could Not create the java virtual machine"
      If unset mapred.child.java.opts everything runs fine. I've even tried the same thing on c1.xlarge instances but with the same result.
      I'll add full logs. I need to set mapred.child.java.opts becuase my reduce program are memory hungry.

      I've been trying to setup a map-reduce cluster on ec2 for last two days via whirr, but this error was recurring. At first I thought It might be whirr
      specific, but manual ec2 cluster also resulted in same.
