+ * This example demonstrates data rebalance on new nodes.
+ *
+ * - Start 3 nodes (A, B, C)
+ * - Put some data
+ * - Add 2 new nodes (D, E)
+ * - Set new baseline to (A, D, E)
+ * - Stop (B, C)
+ * - Check that data is still available on the new configuration
+ *
+ *
+ * To run the example, do the following:
+ *
+ * - Import the examples project into you IDE.
+ * - Run the example in the IDE.
