[jira] [Created] (CARBONDATA-2372) Potential division by zero in InputProcessorStepForPartitionImpl#partitionInputReaderIterators

Ted Yu created CARBONDATA-2372:
----------------------------------

             Summary: Potential division by zero in InputProcessorStepForPartitionImpl#partitionInputReaderIterators
                 Key: CARBONDATA-2372
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-2372
             Project: CarbonData
          Issue Type: Bug
            Reporter: Ted Yu


{code}
    int parallelThreadNumber = Math.min(inputIterators.length, numberOfCores);
{code}
parallelThreadNumber is later used in:
{code}
      iterators[i % parallelThreadNumber].add(inputIterators[i]);
{code}
We should check that parallelThreadNumber is not zero before the division.
