Summary: [HBCK2] Add RecoveredEditsPlayer
Key: HBASE-22976
URL: https://issues.apache.org/jira/browse/HBASE-22976
Project: HBase
Issue Type: Bug
Components: hbck2
Reporter: stack
We need a recovered edits player. Messing w/ the 'adoption service' -- tooling
to adopt orphan regions and hfiles -- I've been manufacturing damaged clusters
by moving stuff around under the running cluster. No reason to think that an
hbase couldn't lose accounting of a whole region if a cataclysm. If so, region
will have stuff like the '.regioninfo', dirs per column family w/ store files
but it could too have a 'recovered_edits' directory with content in it. We have
a WALPlayer for errant WALs. We have the FSHLog tool which can read
recovered_edits content for debugging data loss. Missing is a
RecoveredEditsPlayer.
I took a look at extending the WALPlayer since it has a bunch of nice options
and it can run at bulk. Ideally, it would just digest recovered edits content
if passed an option or recovered edits directories. On first glance, it didn't
seem like an easy integration.... Would be worth taking a look again. Would be
good if we could avoid making a new, distinct tool, just for Recovered Edits.
