Semyon Danilov updated IGNITE-14347:
------------------------------------
Description:
When a node sees an object of a class that is missing on this node's classpath,
it fails with the following exception:
{noformat}

The result is that one node can write an object of some custom class to the
metastorage and make all other nodes fail.
The following reproducer can be used:
{code:java}
public class ClientNode {
public static void main(String[] args) throws IgniteCheckedException {
IgniteConfiguration igniteCfg = nodeConfiguration().setClientMode(true);
IgniteKernal ignite = (IgniteKernal) Ignition.start(igniteCfg);
DistributedMetaStorage metaStorage =
ignite.context().distributedMetastorage();
metaStorage.write("hey", new BamboozleClass());
}
private static IgniteConfiguration nodeConfiguration() {
IgniteConfiguration igniteCfg = new IgniteConfiguration();
TcpDiscoverySpi discoverySpi = new TcpDiscoverySpi();
discoverySpi.setIpFinder(new TcpDiscoveryVmIpFinder()
.setAddresses(Collections.singleton("127.0.0.1:47500..47600")));
igniteCfg.setDiscoverySpi(discoverySpi);
return igniteCfg;
}
public static class BamboozleClass implements Serializable {
}
}{code}
