Class AmazonElasticMapReduceClient

java.lang.Object
  com.amazonaws.AmazonWebServiceClient
      com.amazonaws.services.elasticmapreduce.AmazonElasticMapReduceClient

All Implemented Interfaces:: AmazonElasticMapReduce

Direct Known Subclasses:: AmazonElasticMapReduceAsyncClient

public class AmazonElasticMapReduceClient
extends AmazonWebServiceClient
implements AmazonElasticMapReduce
extends AmazonWebServiceClient
implements AmazonElasticMapReduce

Client for accessing AmazonElasticMapReduce. All service calls made using this client are blocking, and will not return until the service call completes.

This is the Amazon Elastic MapReduce API Reference . This guide provides descriptions and samples of the Amazon Elastic MapReduce APIs.

Amazon Elastic MapReduce (Amazon EMR) is a web service that makes it easy to process large amounts of data efficiently. Amazon EMR uses Hadoop processing combined with several AWS products to do tasks such as web indexing, data mining, log file analysis, machine learning, scientific simulation, and data warehousing.

Field Summary
`protected List<com.amazonaws.transform.JsonErrorUnmarshaller>`	`jsonErrorUnmarshallers` List of exception unmarshallers for all AmazonElasticMapReduce exceptions.

Fields inherited from class com.amazonaws.AmazonWebServiceClient
`client, clientConfiguration, endpoint, LOGGING_AWS_REQUEST_METRIC, requestHandler2s, timeOffset`

Constructor Detail

AmazonElasticMapReduceClient

public AmazonElasticMapReduceClient()

Constructs a new client to invoke service methods on AmazonElasticMapReduce. A credentials provider chain will be used that searches for credentials in this order:

Environment Variables - AWS_ACCESS_KEY_ID and AWS_SECRET_KEY
Java System Properties - aws.accessKeyId and aws.secretKey
Instance profile credentials delivered through the Amazon EC2 metadata service
