----------------------------------------

             Summary: Number of input split threads should always be >= 1
                 Key: GIRAPH-393
                 URL: https://issues.apache.org/jira/browse/GIRAPH-393
             Project: Giraph
          Issue Type: Bug
            Reporter: Alessandro Presta
            Assignee: Alessandro Presta


When the number of input splits is less than the number of workers, integer division in the following snippet means we end up with 0:

{code}
int maxInputSplitThreads =
        inputSplitPathList.size() / getConfiguration().getMaxWorkers();
    int numThreads =
        Math.min(getConfiguration().getNumInputSplitsThreads(),
            maxInputSplitThreads);
{code}
