Zakelly opened a new pull request, #24840:
URL: https://github.com/apache/flink/pull/24840
## What is the purpose of the change
See FLINK-35446. It seems the file merging is disabled, thus the
`FileMergingSnapshotManagerBase#initFileSystem` is never called. And at this
time if we restore from a checkpoint that files are already merged, the managed
path is needed while it has not been initialized. This PR fix this.
## Brief change log
- Skip using managed directory to claim management of files if it is not
initialized, which means the no management need to be claimed in this case.
## Verifying this change
