Description

At line 140:

        } else {
          ta = new TaskAttemptInfo(successful, type, false);

There is no check for type against null.
TaskAttemptInfo ctor deferences type:

  public TaskAttemptInfo(TaskAttempt ta, TaskType type, Boolean isRunning) {
    final TaskAttemptReport report = ta.getReport();
    this.type = type.toString();
