Issue with job submission from Flink Job UI (Exception:org.apache.flink.client.program.OptimizerPlanEnvironment$ProgramAbortException)

问题

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");

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.

When i submit the same job using flink run command, it works fine. No errors.

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

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

Found the issue. I was wrapping my code with

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
};

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

Thanks !
