flink tasks在taskmanager上分布不均衡

我们测试环境的flink集群(flink 1.8)，taskmanager有3个，每个有10个slot。然后我有一个job，其并行度是3，预期是会分布到不同taskmanager的slot上(也就是三个taskmanager各分配一个slot，这样能更好的利用cpu资源). 结果发现这个job的三个task全部分配到同一个taskmanager上了。为什么？有什么配置可以改变这...

flink job task在taskmanager上分布不均衡怎么办？

flink集群(flink 1.10.1)，taskmanager有4个，每个有10个slot。然后我有2个job，每个并行度是4，预期是会分布到不同taskmanager的slot上(也就是4个taskmanager平均分配2个slot，这样能更好的利用cpu资源). 结果发现这2个job的8个task全部分配到同一个taskmanager上了。为什么？有什么配置可以改变这种行为吗？....
