> Poking around, was going to add a 'filesystem' command to hbck2. It would
> take nothing or a list of one or more table names and optionally a path to a
> region. If nothing passed, it would review the fs for corrupt hfiles and bad
> links reporting the bad as it went. If --fix is passed, it will sideline
> corrupt files and mis-links. Would advise reopen/rolling-restart if change
> made. For starters would make use of the hbck1 fs tools added by HBASE-22680.
> Above would exploit the following facillty from hbck1.
> -checkCorruptHFiles
> -sidelineCorruptHFiles
> -fixVersionFile
> -fixReferenceFiles
> -fixHFileLinks
> This would address the following from parent issue at least:
> * Fix hfile link problems...
> * Enumerate store files to determine file level corruption...
> I noticed that the 'read-only' hbck1 tool HBaseFsck which is present in the
> hbase2 codebase actually allows fixes in the filesystem; i.e. you'd run
> HBaseFsck and pass say -fixVersionFile. This is mixed in w/ all the other
> hbck1 noise but an operator should be able to make progress with what is
> there regards hfile corruption, bad links, etc. In other words, could just
> doc this facility in the hbck2 tool point folks to the latent hbck1 HBaseFsck
> if they need to do fixup of the fs (Would be confusing but it exists).
