> In FileStoreCommitImpl, currently, it uses `rename` to support atomic commit.
> But this is not work for object store like S3. We can use RecoverableWriter to support atomic commit for object store.
> We can introduce `AtomicFileCommitter`:
>  * Use RecoverableWriter if FileSystem supports createRecoverableWriter
>  * Use rename if createRecoverableWriter is not supported
