Marko Mikulicic commented on CASSANDRA-2671:
--------------------------------------------
perhaps I didn't mention it explicitly in the report. The number of compacted
files which were deleted was small w.r.t the total number of compacted files
which remained (309).
Or, perhaps you mean that there is no problem because the compaction will be
retried later ? In any case, I think it's wiser not get used to "Fatal
exception" in the logs during normal operation.
(Furthermore I waited more than 10 minutes and the files were not deleted, but
I currently don't have time to reproduce the whole scenario)
(This whole foolproof way to delegate the disk space freeing to the GC is
interesting but I'm not feeling very confortable with it)
