当我手动将它上传到我的集群（使用 UI）时，我有一个运行良好的 flink 作业。
但是当我尝试通过 RestClusterClient 部署它时，它给我一个 ClassNotFoundException 失败（我确实看到该作业出现在集群上，并且失败了）。
val packagedProgram = new PackagedProgram(
new File("/home/laurent/Projects/lead-job-runner/target/lead-0.1-jar-with-dependencies.jar"),
Array("--kafka-bootstrap-servers", "kafka:29092"): _*
)
val configuration = new Configuration()
configuration.setString(JobManagerOptions.ADDRESS, "localhost")
configuration.setString("jobmanager.rpc.port", "6123")
val clusterClient = new RestClusterClient[StandaloneClusterId](
configuration,
StandaloneClusterId.getInstance()
)
clusterClient.run(packagedProgram, 2)
以下是jobmanager的日志：

有问题的类确实不是 jar 中的包（它是一个 scala 匿名函数类）。
但是……为什么与使用完全相同的胖罐子的 RestClusterClient 相比，手动启动作业时运行良好？
另外，在将 flink 日志级别设置为 DEBUG 时，我在 IntelliJ 中看到很多日志，如下所示：
DEBUG org.apache.flink.streaming.api.graph.StreamGraphGenerator - Transforming TwoInputTransformation{id=17, name='process-control-operator', outputType=Java Tuple2<scala.Tuple2(_1: String, _2: String), GenericType<eu.euranova.model.ShareEvent>>, parallelism=2}

...这似乎表明至少“驱动程序”在本地运行，而任务被发送到集群（另一种解释是集群将所有日志发送回 RestClusterClient，我发现它没有链接）
你知道是什么原因造成的吗？我怎样才能让它发挥作用？
在此先感谢您的帮助。
此致，
