Jonas Borgström commented on CASSANDRA-3466:
--------------------------------------------
> Do you observe the same behavior if both nodes start life as 1.x?
No. Hinted handoff seems to work well if I either start with 1.0.2 nodes or
restart all nodes once all nodes have been upgraded to 1.0.2. Probably
something in the gossip state confusing hinted hand-offs.
> Is node2 down long enough for node1 failure detector to notice? (i.e. shows
> as DOWN in nodetool ring)
Yes. This from the node1 log:
{code}
Node2 is shut down
INFO 19:39:08,331 InetAddress /127.0.0.2 is now dead.
Hint is triggered using set bar[x][x]='x'
INFO 19:40:52,126 Node /127.0.0.2 has restarted, now UP
INFO 19:40:52,127 InetAddress /127.0.0.2 is now UP
INFO 19:40:52,127 Node /127.0.0.2 state jump to normal
Nothing happens, hint stays in HintsColumnFamily forever
{code}
Calling deliverHints() using JMX also does not seem to work. Restarting node1
will though...
> 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: 1.0.2
> Reporter: Jonas Borgström
> Labels: hintedhandoff
>
> 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)
