Question

我正在尝试使用Kubernetes设置集群（Apache Flink 1.6.1）并在运行作业时出现以下错误：

2018-10-09 14:29:43.212 [main] INFO  org.apache.flink.runtime.entrypoint.ClusterEntrypoint  - --------------------------------------------------------------------------------
2018-10-09 14:29:43.214 [main] INFO  org.apache.flink.runtime.entrypoint.ClusterEntrypoint  - Registered UNIX signal handlers for [TERM, HUP, INT]
Exception in thread "main" java.lang.NoSuchMethodError: org.apache.flink.runtime.entrypoint.ClusterConfiguration.<init>(Ljava/lang/String;Ljava/util/Properties;[Ljava/lang/String;)V
    at org.apache.flink.runtime.entrypoint.EntrypointClusterConfiguration.<init>(EntrypointClusterConfiguration.java:37)
    at org.apache.flink.container.entrypoint.StandaloneJobClusterConfiguration.<init>(StandaloneJobClusterConfiguration.java:41)

    at org.apache.flink.container.entrypoint.StandaloneJobClusterEntryPoint.main(StandaloneJobClusterEntryPoint.java:153)

我的工作将配置文件（file.properties）作为参数。在独立模式下可以正常工作，但显然Kubernetes集群无法解析

job-cluster-job.yaml：

args: ["job-cluster", "--job-classname", "com.test.Abcd", "-Djobmanager.rpc.address=flink-job-cluster",
       "-Dparallelism.default=1", "-Dblob.server.port=6124", "-Dquery.server.ports=6125", "file.properties"]

该如何解决？

更新：该作业是为Apache 1.4.2构建的，因此调查可能是问题所在。

Answer 1

该作业是为1.4.2构建的，似乎在1.6.1（https://github.com/apache/flink/commit/ab9bd87e521d19db7c7d783268a3532d2e876a5d#diff-d1169e00afa40576ea8e4f3c472cf858）中添加了带有错误（EntrypointClusterConfiguration.java）的类，所以这引起了问题。我们更新了作业的依赖关系以指向新的1.6.1版本，并且正确解析了参数。
