我正在尝试使用Helm图表设置Flink Cluster（在2台机器上） . 我给了service.yaml，jobmanager-deployment.yaml和两个taskmanager-deployment.yaml文件 . 我能够看到Jobmanager仪表板UI，但我看到0个taskmanagers而不是2 .
当我检查taskmanager日志时，我看到以下错误：
2018-03-13 06:09:01,035 ERROR org.apache.flink.runtime.taskmanager.TaskManager - Failed to run TaskManager.

这里，
helm-jobmanager-rpc
是JOBMANAGER_RPC_ADDRESS环境变量（在部署yamls中），我用它来设置pods的flink-conf.yaml中的jobmanager.rpc.address属性 . 为什么在使用helm部署时，taskmanager pod无法解析它？
如果我尝试使用 kubectl create -f 命令进行部署，则此配置可正常工作 .
如果需要更多信息，请告诉我 .
