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? > Hinted handoff sends over 1000 rows for one column change > --------------------------------------------------------- > > Key: CASSANDRA-5179 > URL: https://issues.apache.org/jira/browse/CASSANDRA-5179 > Project: Cassandra > Issue Type: Bug > Components: Core > Affects Versions: 1.2.2 > Environment: Windows 7 > Java 1.6u38 > Reporter: Antti Koivisto > Assignee: Aleksey Yeschenko > Fix For: 1.2.3 > > Attachments: cassandra_receiver.log, cassandra_sender.log > > > 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>" -- This message is automatically generated by JIRA.
