Hi 大家好： 在使用flink过程中，运行官网给的命令 https://ci.apache.org/projects/flink/flink-docs-stable/ops/deployment/yarn_setup.html#run-a-single-flink-job-on-yarn 报错如下：
➜ flink-1.8.1 ./bin/flink run -m yarn-cluster ./examples/batch/WordCount.jar ------------------------------------------------------------ The program finished with the following exception: java.lang.RuntimeException: Could not identify hostname and port in 'yarn-cluster'. at org.apache.flink.client.ClientUtils.parseHostPortAddress(ClientUtils.java:47) at org.apache.flink.client.cli.AbstractCustomCommandLine.applyCommandLineOptionsToConfiguration(AbstractCustomCommandLine.java:83) at org.apache.flink.client.cli.DefaultCLI.createClusterDescriptor(DefaultCLI.java:60) at org.apache.flink.client.cli.DefaultCLI.createClusterDescriptor(DefaultCLI.java:35) at org.apache.flink.client.cli.CliFrontend.runProgram(CliFrontend.java:224) at org.apache.flink.client.cli.CliFrontend.run(CliFrontend.java:213) at org.apache.flink.client.cli.CliFrontend.parseParameters(CliFrontend.java:1050) at org.apache.flink.client.cli.CliFrontend.lambda$main$11(CliFrontend.java:1126) at org.apache.flink.runtime.security.NoOpSecurityContext.runSecured(NoOpSecurityContext.java:30) at org.apache.flink.client.cli.CliFrontend.main(CliFrontend.java:1126) 疑问： 1.为什么会将 yarn-clustet解析为host? 2.要运行single flink job on yarn的正确姿势是啥？ Best, Yuhuan
