    Description

      The getMajorityFormat method of the FeCatalogUtils currently returns non-deterministic results when its argument is a list of partitions where there is no numerical majority in terms of the number of instances. The result is determined by the order in which the partitions are added to the HashMap. We need more deterministic results which also considers the memory requirement among different types of partitions. Ideally, this function should return the format with higher memory requirements in case of a tie.
