The leakage results in deleted sstables being opened until shutdown, and disk
space isn't released. That's because column_family::rebuild_sstable_list()
will not remove reference to deleted sstables if an exception was triggered in
sstables::delete_atomically(). A sstable only has its files closed when its
object is destructed.
The exception happens when a major compaction is issued in parallel to a
regular one, and one of them will be unable to delete a sstable already deleted
by the other. That results in remove_by_toc_name() triggering boost::filesystem
::filesystem_error because TOC and temporary TOC don't exist.
We wouldn't have seen this problem if major compaction were going through
compaction manager, but remove_by_toc_name() and rebuild_sstable_list() should
be made resilient.
Fixes #1840.
