Gary Dusbabek commented on CASSANDRA-1904:
------------------------------------------
I reproduced the original error by removing the statistics db in my database.
I still think the right approach is to make sure that
CFS.scrubDataDirectories() includes index CFs.
FWIW empty files will cause problems all over the place, not just at that
particular spot. The approach that has worked so far is to 'scrub' the
directories of undesired files at startup rather than address all the places in
the code where we've assumed the files in the directories are healthy and
supposed to be there.
> Crash during startup: SSTable doesn't handle corrupt (empty) tmp files
