>
> The usefulness of the AddFilesWithMissingEntries utility is questionable.
> #) it's very dangerous: it updates the metadata table of online tablets without checking or warning users
> #) there's no use case for wanting to re-incorporate abandoned metadata files for the metadata table
> #) the primary use case for this utility is to find abandoned files
> #) the list of files must fit in RAM, which probably requires changing jvm options on large systems
> #) the quality and stability of accumulo has improved to the point where having these sorts of crazy fix-it utilities is more trouble than they are worth
> #) as noted in ACCUMULO-2077, it does not work on multi-volume systems
> It would be nice to look for abandoned files, and it might even be worth doing in the GC on a continuous basis.
