Eric Newton created ACCUMULO-2381:
-------------------------------------
Summary: AddFilesWithMissingEntries needs to just find abandoned
files, or be deleted
Key: ACCUMULO-2381
URL: https://issues.apache.org/jira/browse/ACCUMULO-2381
Project: Accumulo
Issue Type: Bug
Affects Versions: 1.6.0
Reporter: Eric Newton
Priority: Minor
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.
