public class BatchAppmaster
Implementation of application master which can be used to run Spring Batch jobs on Hadoop Yarn cluster.
Application master will act as a context running the Spring Batch job. Order to make some sense in terms of using cluster resources, job itself should be able to partition itself in a way that Yarn containers can be used to split the load.
