-----------------------------------
Summary: Improve GraphPartitionerFactory usage
Key: GIRAPH-785
URL: https://issues.apache.org/jira/browse/GIRAPH-785
Project: Giraph
Issue Type: Bug
Components: graph
Affects Versions: 1.1.0
Reporter: Igor Kabiljo
Priority: Minor
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
