---------------------------------------------------------
bq. the cleaning time is way more long than getting space and sorting.
If the initial batch contains large directory, cleaning such directory already
provides gain compared with current patch since the cleaning this large
directory would be deemed important considering the outcome of the sorting.

>
> Currently CleanerChore cleans the directory in dictionary order, rather than
> from the directory with largest space usage. And when data abnormally
> accumulated to some huge volume in archive directory, the cleaning speed
> might not be enough.
> This proposal is another improvement working together with HBASE-18083 to
> resolve our online issue (archive dir consumed more than 1.8PB SSD space)
