【具体log】 嵌入yarn logs -applicationId application_1603495749855_54023 查询log 如下： Container: container_1603495749855_54018_01_000001 on ******.mercury.corp_8041

LogType:jobmanager.err Log Upload Time:Tue Dec 08 17:49:33 -0800 2020 LogLength:160 Log Contents: Unrecognized VM option 'MaxMetaspaceSize=268435456' Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit.

LogType:jobmanager.out Log Upload Time:Tue Dec 08 17:49:33 -0800 2020 LogLength:0 Log Contents:

【疑惑】 根据log，好像是说java版本不对，Unrecognized VM option 'MaxMetaspaceSize=268435456' 该参数只在1.8以上存在，但我的java就是1.8+的。不知道为什么不能启动。 相同的命令，在1.7.2 flink客户端是可以成功启动 【备注】 flink1.7.2同时在使用中，并连接Hadoop在运行flink job 不知道和这个有关系没。

谢谢！
