你好,这个问题需要把javax.ws.rs-api-2.0.jar 对应版本的包放到$FLINK_HOME/lib下 在2019年5月12日 11:05，naisili Yuan<[email protected]> 写道： 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： 2019-05-12 11:02:39,056 INFO org.apache.flink.configuration.GlobalConfiguration -
