Michael Stack commented on HBASE-22976:
---------------------------------------
hbck doesn't work properly against hbase2.
Have you tried changing the code that tries to parse the file name so it is
more accommodating of the filenames under recovered.edits [~mbz] ? Just skip
the time compare stuff and add it to the result list.
If you are unable to put your changes out on the cluster and are having trouble
trying them inside MR, shout and I'll tell you how I got it to work recently
for myself.
> [HBCK2] Add RecoveredEditsPlayer

> Reporter: Michael Stack
> Priority: Major
>
> 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.
> The bulkload tool expects hfiles in column family directories. Recovered
> edits files are not hfiles and the files are x-columnfamily so this is not
> the way to go though a bulkload-like tool that moved the recovered edits
> files under the appropriate region dir and asked the region reopen would be a
> possibility (Would need the bulk load complete trick of splitting input if
> the region boundaries in the live cluster do not align w/ those of the errant
> recovered edits files).
