Package org.apache.ignite.examples.computegrid

Class ComputeTaskMapExample

  • public class ComputeTaskMapExample
extends java.lang.Object
    Demonstrates a simple use of Ignite with ComputeTaskAdapter.

    Phrase passed as task argument is split into words on map stage and distributed among cluster nodes. Each node computes word length and returns result to master node where total phrase length is calculated on reduce stage.

    Remote nodes should always be started with special configuration file which enables P2P class loading: 'ignite.{sh|bat} examples/config/example-ignite.xml'.

    Alternatively you can run ExampleNodeStartup in another JVM which will start node with examples/config/example-ignite.xml configuration.
