Utils.sortTopN does not handle single-element arrays #439

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago

This caused IllegalArgumentException in Utils.partialQuickSort when picking a 
random pivot.  I noticed this specifically in queries of the form: "SELECT 
column FROM table ORDER BY column".  Fix and unit test attached.
