             Summary: Anticompaction race can leak sstables/txn
                 Key: CASSANDRA-13688
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-13688
             Project: Cassandra
          Issue Type: Bug
            Reporter: Blake Eggleston
            Assignee: Blake Eggleston
             Fix For: 4.0


At the top of {{CompactionManager#performAntiCompaction}}, the parent repair 
session is loaded, if the session can't be found, a RuntimeException is thrown. 
This can happen if a participant is evicted after the IR prepare message is 
received, but before the anticompaction starts. This exception is thrown 
outside of the try/finally block that guards the sstable and lifecycle 
transaction, causing them to leak, and preventing the sstables from ever being 
removed from View.compacting.
