             Summary: GiraphInputFormat#getSplits() should be aware of multithreaded input
                 Key: GIRAPH-530
                 URL: https://issues.apache.org/jira/browse/GIRAPH-530
             Project: Giraph
          Issue Type: Bug
            Reporter: Alessandro Presta


The current signature of getSplits() assumes that the only piece of information needed in
order to determine the number of splits is the number of workers.
With multiple input threads for each worker, this is no longer the case.
We could solve this very simply by renaming the numWorkers parameter to something like minSplitCountHint,
and changing any existing callers to pass the total number of input threads instead of workers.
