[ https://issues.apache.org/jira/browse/HBASE-22976?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Michael Stack updated HBASE-22976: -- Release Note: WALPlayer can replay the content of recovered.edits directories. Side-effect is that WAL filename timestamp is now factored when setting start/end times for WALInputFormat; i.e. wal.start.time and wal.end.time values on a job context. Previous we looked at wal.end.time only. Now we consider wal.start.time too. If a file has a name outside of wal.start.time<->wal.end.time, it'll be by-passed. This change-in-behavior will make it easier on operator crafting timestamp filters processing WALs. was:WALPlayer can replay the content of recovered.edits directories. > [HBCK2] Add RecoveredEditsPlayer > > > Key: HBASE-22976 > URL: https://issues.apache.org/jira/browse/HBASE-22976 > Project: HBase > Issue Type: Sub-task > Components: hbck2, walplayer >Reporter: Michael Stack >Assignee: Michael Stack >Priority: Major > Fix For: 3.0.0-alpha-1, 2.3.3, 2.4.0 > > Attachments: 22976.txt > > > We need a recovered edits player.
