> While working on a fix for HUDI-3322, discovered a following issue:
> If we're bootstrapping the MT during pending Rollback operation (this could happen when previous writer had MT *disabled* when writing the data), since bootstrapping is done _after_ Rollback is executed (with its side-effects already being reflected on FS) bootstrapping would incorrectly include intermediary files created by the Rollback (like log-files being created with Rollback Command Block appended).
>
> Filtering of the files is performed here:
> https://github.com/apache/hudi/blob/master/hudi-client/hudi-client-common/src/main/java/org/apache/hudi/metadata/HoodieBackedTableMetadataWriter.java#L752
