-------------------------------------------
Summary: Gossiper#markAlive can race with Gossiper#markDead
Key: CASSANDRA-15059
URL: https://issues.apache.org/jira/browse/CASSANDRA-15059
Project: Cassandra
Issue Type: Bug
Reporter: Blake Eggleston
Assignee: Blake Eggleston
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.
