             Summary: Fix positive random int generation
                 Key: FLINK-4668
             Project: Flink
          Issue Type: Bug
          Components: Client
            Reporter: Alexander Pivovarov
            Priority: Trivial

According to java spec
{code}Math.abs(Integer.MIN_VALUE) == Integer.MIN_VALUE{code}

So, {code}Math.abs(rnd.nextInt()){code} might return negative value

To generate positive random int value we can use 

Integer.MAX_VALUE will be excluded btw
