Hi,You can have multiple Flink clusters on the same set of physical machines. In our experience, it's best to deploy a separate Flink cluster for each job and adjust the resource accordingly.

However, the cluster is running other jobs and in this case it won't have hardware resource for other jobs.On Wed, Oct 24, 2018 at 2:20 PM Kien Truong <duckientruong@xxxxxxxxx> wrote:Hi,
How are your task managers deploy ?
If you cluster only have one task manager with one slot in each node,
then the job should be spread evenly.
