Disabling hinted handoff doesn't work in 0.8.4?
We just tried to disable hinted handoff by setting:
hinted_handoff_enabled: false
in all the nodes of our cluster and restarting them. When they come back up, we continue to see things like this:
INFO [HintedHandoff:1] 2011-09-10 22:41:40,813 HintedHandOffManager.java (line 323) Started hinted handoff for endpoint /10.1.2.3
INFO [HintedHandoff:1] 2011-09-10 22:41:40,813 HintedHandOffManager.java (line 379) Finished hinted handoff of 0 rows to endpoint /10.1.2.3
INFO [HintedHandoff:1] 2011-09-10 22:41:45,025 HintedHandOffManager.java (line 323) Started hinted handoff for endpoint /10.2.3.4

INFO [HintedHandoff:1] 2011-09-10 22:42:10,017 HintedHandOffManager.java (line 323) Started hinted handoff for endpoint /10.3.4.5

Is this a bug with 0.8.4?
Thanks,
Jeremy

Turned out that wasn't a problem - I put some notes on the ticket.

Also I looked at one of the nodes via jmx and checked out the System.HintsColumnFamily and there is activity there. So I created a ticket: https://issues.apache.org/jira/browse/CASSANDRA-3176

I tried looking through the source to see if the log statements would happen regardless but it doesn't look like it. Also I looked at one of the nodes via jmx and checked out the System.HintsColumnFamily and there is activity there. So I created a ticket: https://issues.apache.org/jira/browse/CASSANDRA-3176
