Raúl Kripalani commented on IGNITE-1238:
----------------------------------------
Hey Valentin, do we have a test case that demonstrates what's wrong? If not,
could you give me a hint on how to build such a test case? I think that would
be the starting point. Thanks.
> Joining node should be discarded in case discovery exchange data can't be

> 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.
