> Improve GraphPartitionerFactory usage
> --------------------------------------
>
> Key: GIRAPH-785
> URL: https://issues.apache.org/jira/browse/GIRAPH-785
> Project: Giraph
> Issue Type: Improvement
> Components: graph
> Affects Versions: 1.1.0
> Reporter: Igor Kabiljo
> Priority: Minor
> Attachments: partition_patch.txt
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> 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
