Flink on Yarn启动的TaskManager只有一个

Flink On Yarn 模式，单个任务提交的时候，任务提交成功了，但是我的TaskManager只启动了一个，其他的TaskManager都没启动起来，当然资源也没法用，这是为什么啊？？？
我的启动命令是这样的：flink -m yarn-cluster -yn 3 sse.jar
命名要启动三个TaskManager，但是只启动了一个，我的配置如下：


fs.hdfs.hadoopconf: /etc/hadoop/conf


akka.ask.timeout:20s

# The heap size for the JobManager JVM

jobmanager.heap.size: 2048m


# The heap size for the TaskManager JVM

taskmanager.heap.size: 4096m


# The number of task slots that each TaskManager offers. Each slot runs one parallel pipeline.

taskmanager.numberOfTaskSlots: 12

slaves：

172.16.0.18
172.16.0.19
172.16.0.20
172.16.0.17
