Ruoran Wang created CASSANDRA-11548:
---------------------------------------

             Summary: Anticompaction not removing old sstables
                 Key: CASSANDRA-11548
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11548
             Project: Cassandra
          Issue Type: Bug
         Environment: 2.1.13
            Reporter: Ruoran Wang


1. 12/29/15 https://issues.apache.org/jira/browse/CASSANDRA-10831
Moved markCompactedSSTablesReplaced out of the loop ```for (SSTableReader 
sstable : repairedSSTables)```

2. 1/18/16 https://issues.apache.org/jira/browse/CASSANDRA-10829
Added unmarkCompacting into the loop. ```for (SSTableReader sstable : 
repairedSSTables)```

I think the effect of those above change might cause the 
markCompactedSSTablesReplaced fail on 

DataTracker.java
```
            assert newSSTables.size() + newShadowed.size() == newSSTablesSize :
                String.format("Expecting new size of %d, got %d while replacing 
%s by %s in %s",
                          newSSTablesSize, newSSTables.size() + 
newShadowed.size(), oldSSTables, replacements, this);
```

Since change CASSANDRA-10831 moved it out. This AssertError won't be caught, 
leaving the oldsstables not removed. (Then this might cause row out of order 
error when doing incremental repair if there are L1 un-repaired sstables.)
