             Summary: Preview repair should include sstables from finalized 
incremental repair sessions
                 Key: CASSANDRA-15553
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-15553
             Project: Cassandra
          Issue Type: Bug
          Components: Consistency/Repair
            Reporter: Marcus Eriksson
            Assignee: Marcus Eriksson


When running a preview repair we currently grab all repaired sstables, problem 
is that we depend on compaction to move the sstables from pending to repaired 
so we might have different data marked repaired on different nodes. Including 
any sstables from finalized incremental repair sessions as repaired will solve 
this.

Another problem is that validations don't start at exactly the same time on 
different nodes, so if an incremental repair finishes while the preview repair 
is running we might also validate the wrong repaired set. We should fail the 
preview repair if an intersecting incremental repair finishes during the 
preview repair.
