Aleksey Yeschenko commented on CASSANDRA-5179:
----------------------------------------------

4881221363f984ab6610756cab38e1a016b79e15 (CASSANDRA-4761) broke it. Current 
pagination logic doesn't deal well with the fact that deleteHint is now being 
called from a response handler callback and can go through the same hint again 
and again and again until it's finally replaced with a tombstone. This becomes 
really visible in multi-dc setups, where it can take a while to complete the 
write, but I was able to trigger it with ccm as well (the same hint got sent up 
to 3 times).

Should we reopen CASSANDRA-4761 or deal with it here?

> We have a small test environment with two datacenters (DC1 and DC2) running 
> on Windows 7 laptops.
> Both datacenters have one node. We use network topology strategy to replicate 
> all data to both datacenters.
> We started with empty db. 
> 1. Created a keyspace with strategy options [DC1:1, DC2:1]
> 2. Added one row to a column family with CLI to DC1. Change was replicated to 
> DC2.
> 3. Disconnected network cable from DC2.
> 4. Gossiper noticed, that other DC is dead.
> 5. Added another row to DC1.
> 6. Reconnected cable on DC2.
> 7. DC1 started hinted handoff for DC2.
> 8. Hinted handoff is finished with message: "Finished hinted handoff of 1969 
> rows to endpoint <DC2 ip>"
> We repeated test with same results on Linux cluster with Cassandra 1.2.0. 
> On Cassandra 1.1.5 Linux cluster, only one row was sent to endpoint. 
> "Finished hinted handoff of 1 rows to endpoint <DC2 ip>"
