> TaskInProgress.incompleteSubTask has the following unreachable-code :
> {noformat}
> if (taskState != TaskStatus.State.FAILED &&
> taskState != TaskStatus.State.KILLED &&
> taskState != TaskStatus.State.FAILED_UNCLEAN &&
> taskState != TaskStatus.State.KILLED_UNCLEAN) {
> LOG.info("Task '" + taskid + "' running on '" + trackerName +
> "' in state: '" + taskState + "' being failed!");
> status.setRunState(TaskStatus.State.FAILED);
> taskState = TaskStatus.State.FAILED;
> }
> {noformat}
> It would never reach this code, because it is never called from other places, where taskState is not FAILED, KILLED, FAILED_UNCLEAN and KILLED_UNCLEAN.
> Also status != null is not required, since status is never null.
