-------------------------------------------
Summary: 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: Valentin Kulichenko
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.
