-------------------------------
Ok, at a second thought I think I got your point [~huaxiang], but here we need
to return a result opposite to Long.compare. And I think a direct line here
would be better for readability.
> Improve CleanerChore to clean from directory which consumes more disk space
> ---------------------------------------------------------------------------

> Key: HBASE-18084
> URL: https://issues.apache.org/jira/browse/HBASE-18084
> Project: HBase
> Issue Type: Bug
> Reporter: Yu Li
> Assignee: Yu Li
> Attachments: HBASE-18084.patch, HBASE-18084.v2.patch
>
>
> 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)
