> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Felix N
> Assignee: Felix N
> Priority: Minor
> Labels: pull-request-available
>
> # BlockIteratorImpl#getSubdirEntries sorts by strings, meaning subdir20 comes
> before subdir4, which can result in a bigger block id being listed before a
> smaller block id
> # If block cleanup happens before state.curEntry is reset to null, stale
> data can carry over into the next loop
> # Search for a bigger ID than the range in nextSorted(entries,
> state.curEntry) -> null -> subdir is skipped.
> Usually happens during DiskBalancer operations.
