Ted Yu created FLINK-3928:
-----------------------------

             Summary: Potential overflow due to 32-bit int arithmetic
                 Key: FLINK-3928
                 URL: https://issues.apache.org/jira/browse/FLINK-3928
             Project: Flink
          Issue Type: Bug
            Reporter: Ted Yu
            Priority: Minor


The following pattern occurs in both LocalClusteringCoefficient.java and TriangleListing.java :
{code}
    int scale = parameters.getInt("scale", DEFAULT_SCALE);
...
    long vertexCount = 1 << scale;
{code}
"1 << scale" may overflow with type "int" due to the use of 32-bit arithmetic
