Flink distributes tasks to one taskmanager until slots is full

Flink distributes tasks to one taskmanager until slots is full



I have a flink cluster with 5 nodes. And each nodes have 8 slots. I am using Flink 1.5.2.



If there are N tasks, the problem is that:



If N <= 8, all tasks will assign to node1.
New tasks will be assigned to node2 until it is full.etc.
And the other nodes will be empty.



I want all tasks distributed to all nodes balanced. Can anybody help?



Thanks.

The job manager's scheduler is not aware of which task managers the slots belong to, so no, it is not possible balance the distribution of tasks.
