Subject [jira] Commented: (HADOOP-3442) QuickSort may get into unbounded recursion
Date Mon, 09 Jun 2008 03:53:45 GMT

Devaraj Das commented on HADOOP-3442:
-------------------------------------

Some quick questions - what's the complexity in time/space of BatcherSort. For HeapSort, there
is a o.a.h.u.PriorityQueue. Could we use that?
