@greghogan The pictures below are the before and after screenshots. I run the word count job with parallelism 2 and inject an error in the first attempt of Reduce(1/2).

I insert the code before `invokable.invoke();` in `Task#run` of Task.java to create failed jobs:
```
if (taskInfo.getTaskName().contains("Reduce") && taskInfo.getIndexOfThisSubtask() == 0
&& taskInfo.getAttemptNumber() == 0) {
throw new RuntimeException("crash");
}
```
