[jira] [Commented] (HBASE-21893) Space quota: Usage is not
calculated correctly if snapshot is created on a table then table is
deleted and created again
[ https://issues.apache.org/jira/browse/HBASE-21893?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17024593#comment-17024593 ]
Xu Cang commented on HBASE-21893:
---------------------------------
[~a00408367]
Archived file will be deleted after TTL. (setting is this : hbase.master.hfilecleaner.ttl , The period (in milliseconds) to keep store files in the archive folder before deleting them from the file system)
I think the question comes down to if Quota should take archived file into account. If so, there is nothing wrong with above behavior.
