cascading.property.AppProps

Class AppProps is a fluent helper for setting various application level properties that every {@link cascading.flow.Flow} may or may not be required to have set. These properties are typically passed to a Flowvia a {@link cascading.flow.FlowConnector}.

New property settings that may be set in Cascading 2 are application name, version, and any tags.

See {@link #addTag(String)} for examples of using tags to help manage an application.

In prior releases, the FlowConnector was responsible for setting the "application jar" class or path. Those methods have been deprecated and moved to AppProps.


    Configuration conf = ( (BaseHadoopPlatform) getPlatform() ).getConfiguration();


    conf.set( AppProps.APP_NAME, "testname" );


    AppProps props = AppProps.appProps().setVersion( "1.2.3" );


    Properties properties = props.buildProperties( conf ); // convert job conf to properties instance


    Flow flow = getPlatform().getFlowConnector( properties ).connect( source, sink, pipe );


    assertEquals( "testname", flow.getProperty( AppProps.APP_NAME ) );
    assertEquals( "1.2.3", flow.getProperty( AppProps.APP_VERSION ) );
