-----------------------------------------
Assignee: Sylvain Lebresne (was: Tyler Hobbs)
> Not all STATUS_CHANGE UP events reported via the native protocol
> ----------------------------------------------------------------
>
> Key: CASSANDRA-5769
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5769
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.2.5, 1.2.6
> Environment: Uubuntu 12.04, x86, 64 bit
> Reporter: Duncan Sands
> Assignee: Sylvain Lebresne
> Priority: Minor
>
> Not all gossip UP events are pushed to native protocol users who have
> registered for them. This seems to be a native protocol issue because nodes
> themselves get the UP event (as seen in their logs). I can consistently
> reproduce this issue as follows:
> 1) connect a client to a cluster node ("node1") using the native protocol,
> register for TOPOLOGY_CHANGE and STATUS_CHANGE events. (Probably you only
> need to register for STATUS_CHANGE to see this, however my client registers
> for both).
> 2) on another node ("node2"), send SIGSTOP to the Cassandra process.
> 3) after about 30 seconds the client gets pushed a STATUS_CHANGE DOWN event
> for the stopped node.
> 4) on node2, send SIGCONT to the the Cassandra process.
> 5) wait forever to get a STATUS_CHANGE UP event. This is failure: no event
> is ever received.
> Observe that node1 does know that node2 is back up: in its system log I see
> for example
> INFO [GossipStage:1] 2013-07-17 14:27:41,238 Gossiper.java (line 771)
> InetAddress /172.18.34.169 is now UP
> shortly after sending SIGCONT to the stopped process.
> To eliminate the possibility that my client is at fault, I performed the
> following sanity check:
> 2') on node2, stopped Cassandra nicely using: sudo service cassandra stop
> 4') on node2, restarted Cassandra using: sudo service cassandra start
> In this case the client soon after gets a STATUS_CHANGE DOWN event followed
> by a STATUS_CHANGE UP event for node2.
