Valentin Kulichenko commented on IGNITE-1238: --------------------------------------------- Raul, you can use scenario described here to reproduce the issue: https://issues.apache.org/jira/browse/IGNITE-1205. Just replace Visor with an ordinary node started with {{ignite.sh}} (i.e., without additional classes on classpath). This node will join topology, but it should not be able to do this. > Joining node should be discarded in case discovery exchange data can't be > deserialized > -------------------------------------------------------------------------------------- > > Key: IGNITE-1238 > URL: https://issues.apache.org/jira/browse/IGNITE-1238 > Project: Ignite > Issue Type: Bug > Components: general > Affects Versions: 1.1.4 > Reporter: Valentin Kulichenko > Assignee: Raúl Kripalani > Priority: Critical > Fix For: ignite-1.4 > > > Currently a node will join even if unmarshalling fails (see > {{TcpDiscoverySpi.onExchange()}} method, which can cause unexpected > behaviour. For example, a continuous query listener is not deployed on some > nodes in topology. Everything works, but some updates are lost. We should > discard the node in this case and give a good error message to user with > information on how to fix it properly. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
