-----------------------------------
Summary: SharedStateRegistry print too much info log
Key: FLINK-32141
URL: https://issues.apache.org/jira/browse/FLINK-32141
Project: Flink
Issue Type: Bug
Components: Runtime / Checkpointing
Affects Versions: 1.17.0
Reporter: Feifan Wang
Fix For: 1.17.1
Attachments: image-2023-05-21-00-26-20-026.png
FLINK-29095 added some log to SharedStateRegistry for trouble shooting. Among
them, a info log be added when newHandle is equal to the registered one:
[https://github.com/apache/flink/blob/release-1.17.0/flink-runtime/src/main/java/org/apache/flink/runtime/state/SharedStateRegistryImpl.java#L117]
!image-2023-05-21-00-26-20-026.png|width=775,height=126!
But this case cannot be considered as a possible bug, because
FsStateChangelogStorage will directly use the FileStateHandle of the previous
checkpoint instead of PlaceholderStreamStateHandle.
In our tests, JobManager printed so much of this log that useful information
was overwhelmed.
So I suggest change this log level to trace, WDYT [~Yanfei Lei], [~klion26] ?
