Ted Yu updated KYLIN-2893:
--------------------------
Description:
{code}
if (hitFrequencyMap.get(cuboid) != null) {
tmpCuboidHitProbabilityMap.put(cuboid, unitUncertainProb
+ (1 - WEIGHT_FOR_UN_QUERY) *
hitFrequencyMap.get(cuboid) / totalHitFrequency);
{code}
We should check that totalHitFrequency is not zero before performing division.
