Jonas Borgström commented on CASSANDRA-3466: -------------------------------------------- bq. Hints aren't delivered immediately, there's up to a 60s random delay to stagger the replay. Did you wait long enough to be sure it passed? Yes, I've waited a couple of minutes now and still nothing. So I guess issuing "nodetool flush" isn't enough. I'll leave it running while I recompile with your changes and re-test. > Hinted handoff not working after rolling upgrade from 0.8.7 to 1.0.2 > -------------------------------------------------------------------- > > Key: CASSANDRA-3466 > URL: https://issues.apache.org/jira/browse/CASSANDRA-3466 > Project: Cassandra > Issue Type: Bug > Affects Versions: 1.0.0 > Reporter: Jonas Borgström > Assignee: Brandon Williams > Labels: hintedhandoff > Fix For: 1.0.3 > > > While testing rolling upgrades from 0.8.7 to 1.0.2 on a test cluster I've > noticed that hinted hand-off didn't always work properly. Hints generated on > an upgraded node does not seem to be delivered to other newly upgraded nodes > once they rejoin the ring. They only way I've found to get a node to deliver > its hints is to restart it. > Here's some steps to reproduce this issue: > 1. Install cassandra 0.8.7 on node1 and node2 using default settings. > 2. Create keyspace foo with {replication_factor: 2}. Create column family bar > 3. Shutdown node2 > 4. Insert data into bar and verify that HintsColumnFamily on node2 contains > hints > 5. Start node2 and verify that hinted handoff is performed and > HintsColumnFamily becomes empty again. > 6. Upgrade and restart node1 > 7. Shutdown node2 > 8. Insert data into bar and verify that HintsColumnFamily on node2 contains > hints > 9. Upgrade and start node2 > 10. Notice that hinted handoff is *not* performed when "node2" comes back. > (Only if node1 is restarted) -- This message is automatically generated by JIRA.
