Matthias Pohl commented on FLINK-31593: --------------------------------------- [~Yanfei Lei] Roman has a point with temporary folders being referenced in the generated _metadata file: Do we know why this is like that? The state of the checkpoint shouldn't be stored in a temporary folder as far as I understand. The checkpoint should be rather self-contained so that we can safely copy it over into the tests' resources subfolder. [~roman]'s suggestion to disable the changelog statebackend for the checkpoint test runs (i.e. extending the if condition in [SnapshotMigrationTestBase:273|https://github.com/apache/flink/blob/c89e400ae379c8b7490d9af20f82f49319895dce/flink-tests/src/test/java/org/apache/flink/test/checkpointing/utils/SnapshotMigrationTestBase.java#L273]) actually works. Would that be a viable solution? [~Yanfei Lei] Or do we hide a different problem with this issue? I saw that you re-enabled the changelog backend for the tests in [93146a78|https://github.com/apache/flink/commit/93146a78]. > Update reference data for Migration Tests > ----------------------------------------- > > Key: FLINK-31593 > URL: https://issues.apache.org/jira/browse/FLINK-31593 > Project: Flink > Issue Type: Sub-task > Reporter: Matthias Pohl > Assignee: Matthias Pohl > Priority: Major > Labels: pull-request-available > Attachments: > FLINK-31593.StatefulJobSavepointMigrationITCase.create_snapshot.log, > FLINK-31593.StatefulJobSavepointMigrationITCase.verify_snapshot.log > > > # Update {{CURRENT_VERSION in TypeSerializerUpgradeTestBase}} with the new > version.
