Jonas Borgström commented on CASSANDRA-3466: -------------------------------------------- I'm running 1.0.2 with the 3446 patches *and* the following three lines removed from HintedHandOffManager.java (As discussed earlier in this ticket) {code} if (hintStore.getSSTables().isEmpty()) return; // nothing to do, don't confuse users by logging a no-op handoff // An empty line {code} That should explain the line number mismatch (-3). Without this change hinted handoff wouldn't work at all for me unless HintsColumnFamily is large enough to flow to disk before the other node gets back up. > 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 > > Attachments: CASSANDRA-3466-2.tar.gz, CASSANDRA-3466.tar.gz > > > 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.
