> 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}
