Description

DominantResourceFairnessComparator2 was using wrong resource info to get if one queue is needy or not now. We should fix it.

      boolean s1Needy = resourceInfo1[dominant1].getValue() <
          minShareInfo1[dominant1].getValue();
      boolean s2Needy = resourceInfo1[dominant2].getValue() <
          minShareInfo2[dominant2].getValue();
