Purushottam Sinha commented on FLINK-39500:
-------------------------------------------
The description would some refactoring after SeaweedFS adaption, after
FLINK-39499 is done.
> test_batch_wordcount.sh presto and presto_minio variants fail due to FileSink
> batch mode requiring recoverable writer
> ---------------------------------------------------------------------------------------------------------------------

> Key: FLINK-39500
> URL: https://issues.apache.org/jira/browse/FLINK-39500
> Project: Flink
> Issue Type: Technical Debt
> Components: Tests
> Reporter: Martijn Visser
> Priority: Major
>
> - The presto and presto_minio variants of test_batch_wordcount.sh fail at
> plan translation with UnsupportedOperationException: This s3 file system
> implementation does not support recoverable writers
> - flink-examples-streaming WordCount.jar uses FileSink which calls
> createRecoverableWriter unconditionally during getCommittableSerializer, even
> in batch mode.
> - Presto S3 deliberately doesn't support recoverable writers
> - These variants aren't in run-nightly-tests.sh, so the breakage went
> unnoticed. Likely regressed when WordCount was migrated to FileSink (around
> FLINK-24830 era)
> We should consider removing the presto and presto_minio cases from
> test_batch_wordcount.sh
