从Flink作业UI提交作业的问题(异常:org.apache.flink.client.program.OptimizerPlanEnvironment $ ProgramAbortException) [英] Issue with job submission from Flink Job UI (Exception:org.apache.flink.client.program.OptimizerPlanEnvironment$ProgramAbortException)

问题描述

我有用于flink作业的简单Java代码

I have simple java code for flink job

List<Tuple2> list = new ArrayList<>();
for (int i  = 0; i < 10; i++) {
     list.add(new Tuple2(Integer.valueOf(i), "test" + i));
}
StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
env.fromCollection(list).print();
env.execute("job1");

我打包了这段代码并创建了一个jar:说flink-processor-0.1-SNAPSHOT.jar，然后将其从Submit job UI上载到JobManager.上传没有问题.我看到EntryClass具有主类(com.abc.xyz.streaming.FlinkProcessor)现在，我使用一些参数(--ns.conf1 abc.file --ns.conf2 xyz.file)从"Submit Job Ui"提交作业，并指定了主类(com.abc.xyz.streaming.FlinkProcessor).作业提交失败..在JobManager中，我看到以下错误.

I packaged this code and create a jar: say flink-processor-0.1-SNAPSHOT.jar, upload it to JobManager from Submit job UI. No issues in upload. I see the EntryClass has the main class (com.abc.xyz.streaming.FlinkProcessor) Now, i submit the job from "Submit Job Ui "with some params (--ns.conf1 abc.file --ns.conf2 xyz.file) and specified the main class (com.abc.xyz.streaming.FlinkProcessor). The job submission fails. In the JobManager, i see the following errors.

当我使用flink run命令提交同一作业时，它工作正常.没有错误.

flink运行-c com.abc.xyz.streaming.FlinkProcessor/Users/abc/target/flink-processor-0.1-SNAPSHOT.jar --ns.conf1 abc.file --ns.conf2 xyz.文件

不确定我在这里想念什么吗?非常感谢您的帮助.

Not sure what I am missing here? Any help is much appreciated.

推荐答案

发现了问题.我用

try { 
 List<Tuple2> list = new ArrayList<>();
 for (int i  = 0; i < 10; i++) {
     list.add(new Tuple2(Integer.valueOf(i), "test" + i));
 }
 StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
 env.fromCollection(list).print();
 env.execute("job1");
} catch (Throwable t) { 
ignore t
};

更改了异常块尝试{.....} catch(Exception exp){ignore exp}; 此后，它开始工作.

changed the exception block try { ..... } catch (Exception exp) { ignore exp}; After this, it started working.

谢谢！
