Alexey Goncharuk commented on IGNITE-2880:
------------------------------------------
This is related to the absence of continuous handlers peer deployment for the
newly started nodes. While the deployment issue is hard to fix, the example can
be fixed to avoid this - we need to remove remote listeners before the example
stop.

> Key: IGNITE-2880
> URL: https://issues.apache.org/jira/browse/IGNITE-2880
> Project: Ignite
> Issue Type: Bug

> Environment: Ubuntu 14.04, Ignite 1.6.0
> Reporter: Vasilisa Sidorova
>
> ---------------------------------------------
> DESCRIPTION
> ---------------------------------------------
> If you run any messaging example (java or scala) in the cluster and then try
> to run new node from command line the node will be started but gets
> ClassNotFoundException
> ---------------------------------------------
> STEPS FOR REPRODUCE
> ---------------------------------------------
> # Build examples in IDE
> # Run ExampleNodeStartup or ./bin/ignite.sh
> ./examples/config/example-ignite.xml (it doesn't matter)
> # Run any messaging example and wait while it will be finished
> # Run one more node from command line:
> {noformat}
> ./bin/ignite.sh ./examples/config/example-ignite.xml
> {noformat}
> ---------------------------------------------
> ACTUAL RESULT
> ---------------------------------------------
> Node is started but gets ClassNotFoundException:
> {noformat}
