Summary: Two test in StateBackendMigrationTestBase failes
Key: FLINK-11281
URL: https://issues.apache.org/jira/browse/FLINK-11281
Project: Flink
Issue Type: Bug
Reporter: BoWang
Attachments: fail.png
Hi, all.
I found Flink builds got two stable failures in StateBackendMigrationTestBase
of recent PRs, which also occurs in my development environment. The detailed
errors are as follows.
This currently doesn't pass because the ListSerializer doesn't respect the
reconfigured case, yet.
java.lang.UnsupportedOperationException: The serializer should have been
reconfigured as a new instance; shouldn't be used.
