public class TestShortArrays
extends SubOperatorTest

DRILL-5804. Code had a bug that if an array had low cardinality, the average, expressed as an int, was zero. We then allocated a zero length buffer, tried to double it, got another zero length buffer, and looped forever. This test verifies the fixes to avoid that case.
