Dionysios Logothetis resolved GIRAPH-552.
-----------------------------------------
Resolution: Abandoned
> HBaseVertexInputFormat is ignoring region locality on input superstep
> ---------------------------------------------------------------------
>
> Key: GIRAPH-552
> URL: https://issues.apache.org/jira/browse/GIRAPH-552
> Project: Giraph
> Issue Type: Bug
> Components: graph
> Affects Versions: 1.0.0
> Reporter: Brian Femiano
> Priority: Major
>
> During the input superstep, you can see the data for different regions being
> needlessly transferred across the network, instead of giving preference to
> machine-local regions if available.
> On modest to large size graphs (5mil V 10mil E) we've noticed this causing
> resource contention, Zookeeper timeouts, and other issues that often freeze
> the input superstep until manually killed on the task tracker hosts.
> This doesn't happen for TextVertexInputFormat subclasses. Perhaps it has to
> do with each instance of the HBaseVertexInputFormat subclass delegating to a
> private TableInputFormat instance.
