Alan Boudreault commented on CASSANDRA-8683:
--------------------------------------------
I tried this patch to see if this issue was affecting CASSANDRA-8316 or
CASSANDRA-8366, but apparently no. The result of these two issues are the same.
> Ensure early reopening has no overlap with replaced files, and that
> SSTableReader.first/last are honoured universally

> Incremental repairs holds a set of the sstables it started the repair on (we
> need to know which sstables were actually validated to be able to anticompact
> them). This includes any tmplink files that existed when the compaction
> started (if we wouldn't include those, we would miss data since we move the
> start point of the existing non-tmplink files)
> With CASSANDRA-6916 we swap out those instances with new ones
> (SSTR.cloneWithNewStart / SSTW.openEarly), meaning that the underlying file
> can get deleted even though we hold a reference.
> This causes the unit test error:
> http://cassci.datastax.com/job/trunk_utest/1330/testReport/junit/org.apache.cassandra.db.compaction/LeveledCompactionStrategyTest/testValidationMultipleSSTablePerLevel/
> (note that it only fails on trunk though, in 2.1 we don't hold references to
> the repairing files for non-incremental repairs, but the bug should exist in
> 2.1 as well)
