Description

Usage of GraphPartitionerFactory can be improved:

• defining custom partitioner needs extending 3 classes/interfaces, and defining multiple functions, which is more complex than needed
• range partitioners are randomly assigning excess, instead of having each partition/worker having 1 consecutive range
• if maxPartitions is reached, we might be creating number of partitions that is not divisible with number of workers
