Sameer Al-Sakran commented on HADOOP-3442:
------------------------------------------
This bug has hit a lot of our code. One thing I've found is that it depends on
the amount of data per reducer. I.e. tripling the number of reducers causes the
stack overflow to not occur.
> QuickSort may get into unbounded recursion
