Haoze Wu commented on FLINK-31746:
----------------------------------
[~martijnvisser] I reproduced the similar issue in Flink-1.17.0. It has the
similar stage of "Sink Committer (1/1)#0" and the exception can cause this
issue.
> Batch workload output completes while the job client fails

> Key: FLINK-31746
> URL: https://issues.apache.org/jira/browse/FLINK-31746
> Project: Flink
> Issue Type: Improvement
> Affects Versions: 1.14.0
> Reporter: Haoze Wu
> Priority: Major
>
> We are doing testing on Flink-1.14.0 (We know 1.14.0 is not supported now so
> we are also testing Flink-1.17.0 to see if it has the same issue). We run a
> batch processing job. The input of the job is a file in the disk; the output
> of the job is a Kafka topic, which should receive 170 messages when the
> workload finishes. In the testing, we introduce a fault (an IOException) in a
> taskmanager, then the batch processing job client fails:

>
> Such fault during “Split Reader” or “Keyed Aggregation” will trigger this
> “Job failed” message and our Kafka topic can’t receive the complete correct
> output (i.e., less than 170 messages). However, if the exception happens
> during “Sink Unnamed Committer”, the client still recognizes the “Job
> failed”, while our Kafka topic already completely got what it wants.
> We assume that our workload is translated into a few steps: “Custom File
> Source -> Flat Map”, “Keyed Aggregation -> Map -> Sink Unnamed Writer”, and
> “Sink Unnamed Committer”. The last one is responsible for some “commit” for
> it does not affect our end-to-end results. However, the fault in the “commit”
> stage still reports a “failure” to the job client, while the job client may
> get confused.
> We have some questions about the design rationales:
> # In some workloads such as our case, the “commit” at last seems not to
> matter that much. Can it be seen as tolerable?
> # The client log is confusing. It shows tons of exceptions but it does not
> show in which stage of the workload the failure happens. The most useful
> information for the client is something like “Sink Unnamed Committer (1/1)#0
> (7b19f0a2f247b8f38fe9141c9872ef58) switched from RUNNING to FAILED”, which is
> not shown.
