Subject [jira] [Updated] (HBASE-5274) Filter out the expired store file scanner during the compaction

Phabricator updated HBASE-5274:
-------------------------------

    Attachment: D1407.1.patch

Liyin requested code review of "[jira][HBASE-5274] Filter out the expired store file scanner
during the compaction".
Reviewers: Kannan, Karthik, khemani, mbautin

  During the compaction time, HBase will generate a store scanner which will scan a list of
store files. And it would be more efficient to filer out the expired store file since there
is no need to read any key values from these store files.

  This optimization has been already implemented on 89-fb and this is the building block for
HBASE-5199 as well. It is supposed to be no-ops to compact the expired store files.

TEST PLAN
  running all the unit tests
