> When i am testing the {{kubernetes-session.sh}}, i find that the {{KubernetesResourceManager}} will constantly allocate taskmanager after cancel a job. I think it may be caused by a bug of the following code. When the {{dividend}} is 0 and {{divisor}} is bigger than 1, the return value will be 1. However, we expect it to be 0.
> {code:java}
> /**
> * Divide and rounding up to integer.
> * E.g., divideRoundUp(3, 2) returns 2.
> * @param dividend value to be divided by the divisor
> * @param divisor value by which the dividend is to be divided
> * @return the quotient rounding up to integer
> */
> public static int divideRoundUp(int dividend, int divisor) {
> return (dividend - 1) / divisor + 1;
> }{code}
>
> How to reproduce this issue?
> # Start a Kubernetes session
> # Submit a Flink job to the existing session
> # Cancel the job and wait for the TaskManager released via idle timeout
> # More and more TaskManagers will be allocated
