> 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.
