好的，谢谢回复。
想问下，生产环境适合用standalone
cluster模式部署嘛，我感觉集群还是不稳定，10个job跑不了24小时就出问题，基本都是心跳丢失或者slot 被移除之类的问题。
但是我部署flink on yarn又出了问题，自己解决半天也出了问题，希望能得到帮助，我运行bin/yarn-session.sh -jm
1024m -tm 4096m -s 8报错：

而本身yarn和hadoop进程都是启动起来ok的，jps显示如下：
22019 QuorumPeerMain
1971 Jps
24452 ResourceManager
24885 DataNode
29788 HMaster
24687 NameNode
29951 HRegionServe
HADOP_CONF_DIR和YARN_CONF_DIR环境变量也是配置了的
请问如果使用flink on yarn模式的话，flink应该怎么配置，在flink开箱即用的基础上加上什么配置，希望得到指导。
谢谢！
