Delete out of TTL store files before compaction selection
---------------------------------------------------------
Key: HBASE-5199
URL: https://issues.apache.org/jira/browse/HBASE-5199
Project: HBase
Issue Type: Improvement
Reporter: Liyin Tang
Assignee: Liyin Tang
Currently, HBase deletes the out of TTL store files after major compaction. We
can change the sequence to delete the out of TTL store files before selecting
store files for compactions.
In this way, HBase can keep deleting the old invalid store files without major
compaction, and also prevent from unnecessary major compactions since the out
of TTL store files will be deleted before the compaction selection.
