Apache Flink(如何唯一标记作业) [英] Apache Flink (How to uniquely tag Jobs)

问题描述

是否可以用唯一的名称标记作业，以便以后可以停止它们?我真的不想grep并保留作业ID.

Is it possible to tag jobs with a unique name so I can stop them at a later date?. I don't really want to grep and persist Job IDs.

简而言之，我想在部署过程中停止一项工作，然后部署新任务.

In a nutshell I want to stop a job as part of my deployment and deploy the new one.

推荐答案

您可以在 execute(name:String)调用中启动作业时为作业命名，例如

You can name jobs when you start them in the execute(name: String) call, e.g.,

val env: StreamExecutionEnvironment = StreamExecutionEnvironment.getExecutionEnvironment()

val result: DataStream[] = ???       // your job logic
result.addSink(new YourSinkFunction) // add a sink

env.execute("Name of your job")      // execute and assign a name

RESTJobManager的API 提供了作业详细信息列表，其中包括作业名称及其JobId.

The REST API of the JobManager provides a list of job details which include the name of the job and its JobId.
