             Summary: Integer overflow in ShuffleVertexManagerBase
                 Key: TEZ-3666
                 URL: https://issues.apache.org/jira/browse/TEZ-3666
             Project: Apache Tez
          Issue Type: Bug

In function getExpectedStatsInAtIndex, {{statsInMB[index] * numTasks / numVMEventsReceived}}
could cause Integer overflow, for example when statsInMB[index]  == 30000 and numTasks ==
200000.
