Class ComputeReducerExample


  • public class ComputeReducerExample
    extends java.lang.Object
    Demonstrates a simple use of Ignite with reduce closure.

    Phrase is split into words and distributed across nodes where length of each word is calculated. Then total phrase length is calculated using reducer.

    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 Ignite node with examples/config/example-ignite.xml configuration.
