Subject [jira] [Commented] (HBASE-18084) Improve CleanerChore to clean from directory which consumes more disk space
Date Tue, 23 May 2017 02:54:04 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18084?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16020591#comment-16020591

Yu Li commented on HBASE-18084:
-------------------------------

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.

> 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)
