Lukas Nalezenec updated GIRAPH-883:
-----------------------------------

    Description: 
Range partitioners are dividing partitions among maxWorkers workers. But they should divide
partitions only among living workers.



  was:
Range partitioners are dividing partitions among maxWorkers workers. But they should divide
partitions only among living workers.

current code:
      partitionOwners =
          masterGraphPartitioner.createInitialPartitionOwners(
              chosenWorkerInfoList, maxWorkers);

correct code:
      partitionOwners =
          masterGraphPartitioner.createInitialPartitionOwners(
              chosenWorkerInfoList, chosenWorkerInfoList.size());
