----------------------------------------------------
Good catch Thomas!
Looked at the patch, it looks good to me, Hitesh. I think we can have better
names for some of the methods in the test, but I'll pass.
> app master web UI shows reduce task progress 100% even though reducers not

> ran same command as MAPREDUCE-3124. The app master web ui was displaying the
> reduce task progress as 100% even though the states were still
> running/scheduled. Each of those reduce tasks had attempts that failed or
> killed and another one unassigned. Attaching screenshots.
