Aljoscha Krettek commented on FLINK-17775:
------------------------------------------
This is a different issue, {{collect()}} will internally call {{execute()}} on
the environment without giving a name:
https://github.com/apache/flink/blob/fd91220008d29411d8fcc1ffa95eeddc3e6d756a/flink-java/src/main/java/org/apache/flink/api/java/DataSet.java#L413
In your example, your job would execute twice, but the second time without any
operators.
> Cannot set batch job name when using collect

> Key: FLINK-17775
> URL: https://issues.apache.org/jira/browse/FLINK-17775
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Configuration
> Affects Versions: 1.8.3, 1.9.3, 1.10.1
> Reporter: Nikola
> Priority: Critical
>
> We have a batch job in the likes of this:
>
> {code:java}
> ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
> DataSet<Row> dataSet = getDataSet();
> dataSet
> .sortPartition(MyRow::getCount, Order.DESCENDING)
> .setParallelism(1)
> .flatMap(new MyFlatMap())
> .collect();
> env.execute("Job at " + Instant.now().toString());
> {code}
> However, the job name in the flink UI is not "Job at <date>" but the default
> as if I didn't put anything.
>
> Is there way to have my own flink job name?
