----------------------------------------------------

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.

> 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.
