Class JobRunner

java.lang.Object

org.springframework.data.hadoop.mapreduce.JobExecutor

org.springframework.data.hadoop.mapreduce.JobRunner

All Implemented Interfaces:

java.util.concurrent.Callable<java.lang.Void>, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.InitializingBean

public class JobRunner
extends JobExecutor
implements java.util.concurrent.Callable<java.lang.Void>

Simple runner for submitting Hadoop jobs sequentially. By default, the runner waits for the jobs to finish and returns a boolean indicating whether all the jobs succeeded or not (when there's no waiting, the status cannot be determined and null is returned).

For more control over the job execution and outcome consider querying the Jobs or using Spring Batch (see the reference documentation for more info).

To make the runner execute at startup, use setRunAtStartup(boolean).
