[jira] [Updated] (CASSANDRA-15059) Gossiper#markAlive can race with

-----------------------------------------
Reviewers: Ariel Weisberg, Jordan West (was: Ariel Weisberg)
> Gossiper#markAlive can race with Gossiper#markDead
> --------------------------------------------------
>
> Key: CASSANDRA-15059
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15059
> Project: Cassandra
> Issue Type: Bug
> Components: Cluster/Gossip
> Reporter: Blake Eggleston
> Assignee: Blake Eggleston
> Priority: Normal
>
> The Gossiper class is not threadsafe and assumes all state changes happen in a single thread (the gossip stage). Gossiper#convict, however, can be called from the GossipTasks thread. This creates a race where calls to Gossiper#markAlive and Gossiper#markDead can interleave, corrupting gossip state. Gossiper#assassinateEndpoint has a similar problem, being called from the mbean server thread.
