### Search before asking - [X] I searched in the [issues](https://github.com/apache/incubator-paimon/issues) and found nothing similar. ### Motivation At `https://paimon.apache.org/docs/master/maintenance/dedicated-compaction/` It says here `For S3-like object store, its does not have atomic semantic. ` ,so there may be problems with concurrent writes, And I also encountered this situation, specifically in FileStoreCommitImpl.java submit snapshots need to rename the temporary file, if another program also write this snapshot will lead to throw the file already exists exception. code like this  ### Solution s3 does not have a rename interface, generally through the mv implementation, in my impression s3 mv operation is indeed not atomic, but a single file operation should be atomic, so here ,maybe? catch the `FileAlreadyExistsException` and return as false it should, theoretically not affect the subsequent re-create the snapshot operation at HadoopCompliantFileIO.java  ### Anything else? Just a little idea ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
