[jira] Created: (CASSANDRA-532) Flush creates empty SSTables if nothing exists in that CF

Flush creates empty SSTables if nothing exists in that CF
---------------------------------------------------------

                 Key: CASSANDRA-532
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-532
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 0.5
            Reporter: Chris Goffinet
            Assignee: Jonathan Ellis
             Fix For: 0.5


When calling flush() through nodeprobe, we see SSTables being created that are empty for CFs:
