Description
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.
