> Metadata table validator (`HoodieMetadataTableValidator`) throws the
> following exception when there is completed rollback and no completed commits
> in the data table and there is no completed instants in the MDT. In this
> case, both data table and MDT are empty, but the timeline check has a bug
> causing the validation to fail, which is a false positive.
