Matthias Pohl commented on FLINK-32069:
---------------------------------------
I already mentioned it in Slack and will add the comment for completeness here:
Could it be also related to the {{ResultProvider}} that is used within the
{{{}TableResult{}}}? That {{ResultProvider}} seems to depend on the operations
that are processed. It is used within the {{TableResult.await()}} that calls
[TableResultImpl.awaitInternal(..)|https://github.com/apache/flink/blob/c8e6a6f1dc7b7f61e578aa799ee96d383479a9e4/flink-table/flink-table-api-java/src/main/java/org/apache/flink/table/api/internal/TableResultImpl.java#L93].
The latter one waits for {{ResultProvider.isFirstRowReady}} to return true in
[TableResultImpl:105|https://github.com/apache/flink/blob/c8e6a6f1dc7b7f61e578aa799ee96d383479a9e4/flink-table/flink-table-api-java/src/main/java/org/apache/flink/table/api/internal/TableResultImpl.java#L105].
I see three {{ResultProvider}} implementations:
* {{CollectResultProvider}} waits for all the data to be collected before
returning {{true}}
* {{StaticResultProvider}} returns {{true}} right away
* But {{InsertResultProvider}} returns {{true}} after the first data is
processed (which would, in theory, allow the job to still process data)
{{InsertResultProvider}} was also added in 1.15.

> Key: FLINK-32069
> URL: https://issues.apache.org/jira/browse/FLINK-32069
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.16.1, 1.15.4
> Reporter: Aleksandr Iushmanov
> Priority: Major
>
> Using zeppelin with remote cluster I came across some race condition issue
> leading to failed expectations for SQL insert operations.
>
> Below is an example of zeppelin code that is failing because
> jobClient.getJobStatus() returns running even after job has finished. I have
> verified that same failover can happen if I use
> jobClient.getJobExecutionResult().get() (Job execution result is: "Program
> execution finished" but job status is not consistently finished)
> {code:java}
> TableResult tableResult = ((TableEnvironmentInternal)
> tbenv).executeInternal(operations);
> checkState(tableResult.getJobClient().isPresent());
> try {
> tableResult.await();
> JobClient jobClient = tableResult.getJobClient().get();
> if (jobClient.getJobStatus().get() == JobStatus.FINISHED) {
> context.out.write("Insertion successfully.\n");
> } else {
> throw new IOException("Job is failed, " +
> jobClient.getJobExecutionResult().get().toString());
> }
> } catch (InterruptedException e) {
> throw new IOException("Flink job is interrupted", e);
> } catch (ExecutionException e) {
> throw new IOException("Flink job is failed", e);
> } {code}
> ZeppelinCode:
> [https://github.com/apache/zeppelin/blob/master/flink/flink1.15-shims/src/main/java/org/apache/zeppelin/flink/Flink115SqlInterpreter.java#L384]
> I suspect that job status is returned based on runningJobsRegistry and since
> 1.15 this registry is not updated with FINISHED status prior to job result
> future completion, see this change: {{JobMasterServiceLeadershipRunner.java}}
> [https://github.com/apache/flink/pull/18189/files#diff-3eb433f18b85c0f5329a4b312a219583189d777fe9bdd547f1114f4a22989f8bL387]

> It looks like as race condition that is hard to reproduce on lightweight
> setup. I was reproducing this running zeppelin notebook with remote flink
> cluster and triggering SQL insert operation. If I find a smaller setup to
> reproduce on small local cluster with lightweight client, I will update this
> ticket when I have more input. I am open to suggestions on how to fix this.
>
> For Zeppelin I have a separate ticket because Flink 1.15 is not going to be
> fixed but this issue if I understand it correctly should be common for all
> versions starting 1.15, therefore it makes sense to address this starting
> 1.16. https://issues.apache.org/jira/browse/ZEPPELIN-5909
>
> [~mapohl], Thank you for assistance in slack, I have created this ticket to
> back our conversation, could you please add your thoughts on this failure
> mode?
>
> One possible solution would be to have additional check for presence of
> JobResult in Result store before returning jobStatus (if there is a result,
> job shouldn't be reported as running based on this documentation:
> [https://nightlies.apache.org/flink/flink-docs-master/api/java/org/apache/flink/table/api/TableResult.html#await--])
