/**
* Client for accessing AWS Data Pipeline. All service calls made using this
* client are blocking, and will not return until the service call completes.
*
*
* AWS Data Pipeline configures and manages a data-driven workflow called a
* pipeline. AWS Data Pipeline handles the details of scheduling and ensuring
* that data dependencies are met so that your application can focus on
* processing the data.
*
*
* AWS Data Pipeline provides a JAR implementation of a task runner called AWS
* Data Pipeline Task Runner. AWS Data Pipeline Task Runner provides logic for
* common data management scenarios, such as performing database queries and
* running data analysis using Amazon Elastic MapReduce (Amazon EMR). You can
* use AWS Data Pipeline Task Runner as your task runner, or you can write your
* own task runner to provide custom data management.
*
*
* AWS Data Pipeline implements two main sets of functionality. Use the first
* set to create a pipeline and define data sources, schedules, dependencies,
* and the transforms to be performed on the data. Use the second set in your
* task runner application to receive the next task ready for processing. The
* logic for performing the task, such as querying the data, running data
* analysis, or converting the data from one format to another, is contained
* within the task runner. The task runner performs the task assigned to it by
* the web service, reporting progress to the web service as it does so. When
* the task is done, the task runner reports the final success or failure of the
* task to the web service.
*
