>             Project: Flink
>          Issue Type: Bug
>            Reporter: Ted Yu

> 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
