徐波 created DRILL-3168:
-------------------------

             Summary: Char overflow in LimitRecordBatch 
                 Key: DRILL-3168
                 URL: https://issues.apache.org/jira/browse/DRILL-3168
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 0.9.0
            Reporter: 徐波


The variable named 'i' in 'limitWithNoSV' may overflow when fetch - offset > Character.MAX_VALUE - offset. eg. offset=0, fetch=65536. 

Code in limitWithNoSV:
int svIndex = 0;
for(char i = (char) offset; i < fetch; i++) {
      outgoingSv.setIndex(svIndex, i);
      svIndex++;
}
