Michael Stack commented on HBASE-22977:
---------------------------------------
Some stuff I wanted when fixing an old cluster, one that was before hbck2
support. Noting here in case it comes up again or someone else thinks we need
this stuff.
<crazy-pants>
I needed to write a file with a single put/delete edit in it to overwrite a bad
record. A tool that would produce a single hfile w/ a single edit in it would
have been useful. I'd pass it args describing the put/delete I wanted written.
I wanted to stand up the edit region and make arbitrary edits against it. The
cluster was down at the time.

> [HBCK2] hbck2 2.0
> -----------------
>
> Key: HBASE-22977
> URL: https://issues.apache.org/jira/browse/HBASE-22977
> Project: HBase
> Issue Type: Brainstorming
> Reporter: Michael Stack
> Priority: Major
>
> Brainstorming issue for what to ship in an HBCK2 version 2.0 (HBASE-21745
> describes HBCK2 1.0).
> Possibilities:
> * Integrate HBCK2 operations into core either by automating fix or by adding
> shell commands for fixup.
> * An 'adoption service' running in Master where you pass 'orphan data' -- a
> file or a directory -- and the running service figures what to do w/ the
> content (remove if empty, figure where the file should slot if an hfile,
> replay recovered edits if a recovered_edits dir, play WALs if wal dir, etc.).
> Could be smarter/interactive, a 'three-way-merge' as Sean and Josh have
> sketched.
