Jonathan Ellis commented on CASSANDRA-3424:
-------------------------------------------

Hmm.  I don't think there's a quick fix for this.  StorageProxy/ReadVerbHandler doesn't distinguish between "row exists but not the columns you wanted" (should include empty row in the resultset) and "row doesn't exist at all" (should not).
