Xiaolin Ha created HBASE-25363:
----------------------------------

             Summary: Improve performance of HFileLinkCleaner by using ReadWriteLock instead of synchronize
                 Key: HBASE-25363
                 URL: https://issues.apache.org/jira/browse/HBASE-25363
             Project: HBase
          Issue Type: Test
            Reporter: Xiaolin Ha
            Assignee: Xiaolin Ha


HFileLinkCleaner uses synchronized method isFileDeletable, as a result, to cross the cleaner chain, all files will be processed serially. It may block the fork-join thread which scans out some archived files.
