Marcus Eriksson updated CASSANDRA-8124:
---------------------------------------
Attachment: 0001-8124-wip.patch
attaching patch that only converts tmp files into real files when we call
finish() on the SSTableRewriter
the most importart part of the patch is probably the unit tests though
> Stopping a node during compaction can make already written files stay around
> ----------------------------------------------------------------------------

> In leveled compaction we generally create many files during compaction, in
> 2.0 we left the ones we had written as -tmp- files, in 2.1 we close and open
> the readers, removing the -tmp- markers.
> This means that any ongoing compactions will leave the resulting files around
> if we restart. Note that stop:ing the compaction will cause an exception and
> that makes us call abort() on the SSTableRewriter which removes the files.
> Guess a fix could be to keep the -tmp- marker and make -tmplink- files until
> we are actually done with the compaction.
