Hongbo Zeng commented on HELIX-524:
-----------------------------------
I was thinking about the TaskRunner gets the progress from a task and push the
update somewhere (like Kafka). Anyways, this sounds a better plan, I will put
something together for review.
> add getProgress() to Task interface

> Add a getProgress to the Task interface, this is very helpful for long
> running tasks, from which we know the status of a task and see if it's
> blocked. The return value is a double, ranging from 0 to 1.0, 1.0 indicates a
> task is finished
