MartijnVisser opened a new pull request, #29819:
URL: https://github.com/apache/flink/pull/29819
## What is the purpose of the change
Supersedes #26102 by @cnauroth, which was approved but closed as stale after
going out of date with master. It runs the common flink-hadoop-fs integration
test suites against GCS, so the RecoverableWriter behind `FileSink` and
checkpoints on `gs://` gets the same coverage as S3 and OSS.
## Brief change log
- The first commit is #26102 unchanged apart from the ArchUnit store
conflict, with Chris as the author.
- The second commit moves the tests to `GSTestCredentials`
(`IT_CASE_GCS_BUCKET`) from #28286, drops `RequireGCSConfiguration` and the
duplicate behavior suite, removes a duplicate `flink-core` test-jar entry and
adds the missing `@Test` on the two disabled overrides.
- `AbstractHadoopRecoverableWriter(Exception)ITCase` accept a null
`getLocalTmpDir()`. S3 and OSS return a directory, so they behave as before.
## Verifying this change
The GCS ITCases skip unless `IT_CASE_GCS_BUCKET` is set, so CI only compiles
them. I ran them locally on e08a17a9c81 against a private bucket with user
application-default credentials: 35 executed, 4 skipped, 0 failed. Keeping only
the last persisted component on recover fails
`testRecoverAfterMultiplePersistsState` and its multipart variant, while the
existing `GSRecoverableWriterITCase` stays green.
