> If there are any exceptions trying to fork a local task, the exception message is logged but not the stack trace.  There can be a lot of issues forking a process, so we should log the stack trace for better debuggability.
> Code in MapRedLocalTask.executeInChildJVM(DriverContext ctx):
> {code}
>     } catch (Exception e) {
>       e.printStackTrace();
>       LOG.error("Exception: " + e.getMessage());
>       return (1);
>     }
> {code}
