--------------------------------------

             Summary: incorrect debug message in LeveledManifest.java
                 Key: CASSANDRA-4697
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4697
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
    Affects Versions: 1.1.5, 1.0.11
            Reporter: Radim Kolar
            Priority: Trivial


https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/db/compaction/LeveledManifest.java
 line 622.

logger.debug("Estimating {} compactions to do for {}.{}",
new Object[] {Arrays.asList(estimated), cfs.table.name, cfs.columnFamily});

It does not print list as intended. Arrays.asList(estimated).toString() results 
in object reference number, not list itself making debug message useless.

list should be printed by code like this:

   String delim = "";
    for (Item i : list) {
        sb.append(delim).append(i);
        delim = ",";
    }
