    I am doing the steps of Getting started ( http://apacheignite.readme.io/v1.0/docs/getting-started ). But I get this error: Exception Caused by: class org.apache.ignite.IgniteException: Failed to find class with given class loader for unmarshalling.

    Any help would be welcome. Thanks!

    Perhaps you need to move some library from libs/optional to libs. Can you paste the full stack trace here?

    Thanks, Mario. The problem arises when I have more than one node in the cluster and call: try (Ignite ignite = Ignition.start())

    if I call try (Ignite ignite = Ignition.start("examples/config/example-compute.xml")) it works!

    The reason is that your classes are not deployed on remote nodes and peer-class-loading is disabled by default. You can either copy your application Jar files to the "libs" folder on every node, or turn on peer-class-loading.

    For more information about peer-class-loading, please refer to Zero Deployment.
