Justin Ross reassigned QPID-3963:
---------------------------------
Assignee: Justin Ross (was: Ken Giusti)
> A federated broker may not reconnect to a remote cluster on link failure.
> -------------------------------------------------------------------------
>
> Key: QPID-3963
> URL: https://issues.apache.org/jira/browse/QPID-3963
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker, C++ Clustering
> Affects Versions: 0.14
> Reporter: Ken Giusti
> Assignee: Justin Ross
> Fix For: 0.17
>
>
> When a broker is federated with a cluster, the cluster informs the broker of
> the failover addresses that are valid for the cluster. Should a cluster
> member fail, the broker will reconnect to another member of that cluster.
> However, the federated broker only queries the cluster for these failover
> addresses when it first connects to the cluster. Should the cluster topology
> change, the federated broker's list of available failover addresses will
> become out-of-date. This can prevent the broker from correctly re-connecting
> on failure of a cluster member.
> Example:
> Given cluster with members C1 and C2, and a separate broker B, federate B to
> connect to C1. On connecting to C1, B learns the addresses of C2 as an
> alternate failover address. Now shutdown C1. B will reconnect to C2, and
> learn that C2 is the only member of the cluster (ie. no failover addresses).
> After B connects, restart C1 and let it join the cluster. Then shutdown C2.
> Since B does not know that C1 has become available again, B will not
> attempt to re-connect to it. Instead, it tries to reconnect to C2
> indefinately.
> The expected behavior would be to have B reconnect to C1.
