      Description

      In KYLIN-2518, we modify the hash algorithm in the putRowKeyToHLL method in FactDistinictColumnsMapper. This optimization may cause backward compatibility problems because different kylin version may use different hash algorithm and this will cause inaccurate estimation of the number of cuboids.
