Jonathan Ellis reassigned CASSANDRA-3533: ----------------------------------------- Assignee: Brandon Williams (was: Vijay) > TimeoutException when there is a firewall issue. > ------------------------------------------------ > > Key: CASSANDRA-3533 > URL: https://issues.apache.org/jira/browse/CASSANDRA-3533 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: Vijay > Assignee: Brandon Williams > Priority: Minor > Fix For: 1.1.3 > > > When one node in the cluster is not able to talk to the other DC/RAC due to > firewall or network related issue (StorageProxy calls fail), and the nodes > are NOT marked down because at least one node in the cluster can talk to the > other DC/RAC, we get timeoutException instead of throwing a > unavailableException. > The problem with this: > 1) It is hard to monitor/identify these errors. > 2) It is hard to diffrentiate from the client if the node being bad vs a bad > query. > 3) when this issue happens we have to wait for at-least the RPC timeout time > to know that the query wont succeed. > Possible Solution: when marking a node down we might want to check if the > node is actually alive by trying to communicate to it? So we can be sure that > the node is actually alive. -- This message is automatically generated by JIRA.
