### Description of PR 1. BlockIteratorImpl#getSubdirEntries sorts by strings, meaning subdir29 comes before subdir4, which can result in a bigger block id being listed before a smaller block id 2. If block cleanup happens before state.curEntry is reset to null, stale data can carry over into the next loop 3. Search for a bigger ID than the range in nextSorted(entries, state.curEntry) -> null -> subdir is skipped. Usually happens during DiskBalancer operations. ### How was this patch tested?
