How to run Hadoop jobs in Amazon EMR using Eclipse? - eclipse

Question

I have followed the tutorial given by Amazon here but it seems that my code failed to run.
The error that I got:
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
The method withJobFlowRole(String) is undefined for the type AddJobFlowStepsRequest
at main.main(main.java:38)
My full code:
import java.io.IOException;
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.PropertiesCredentials;
import com.amazonaws.services.elasticmapreduce.*;
import com.amazonaws.services.elasticmapreduce.model.AddJobFlowStepsRequest;
import com.amazonaws.services.elasticmapreduce.model.AddJobFlowStepsResult;
import com.amazonaws.services.elasticmapreduce.model.HadoopJarStepConfig;
import com.amazonaws.services.elasticmapreduce.model.StepConfig;
import com.amazonaws.services.elasticmapreduce.util.StepFactory;
public class main {
public static void main(String[] args) {
AWSCredentials credentials = null;
try {
credentials = new PropertiesCredentials(
main.class.getResourceAsStream("AwsCredentials.properties"));
} catch (IOException e1) {
System.out.println("Credentials were not properly entered into AwsCredentials.properties.");
System.out.println(e1.getMessage());
System.exit(-1);
}
AmazonElasticMapReduce client = new AmazonElasticMapReduceClient(credentials);
// predefined steps. See StepFactory for list of predefined steps
StepConfig hive = new StepConfig("Hive", new StepFactory().newInstallHiveStep());
// A custom step
HadoopJarStepConfig hadoopConfig1 = new HadoopJarStepConfig()
.withJar("s3://mywordcountbuckett/binary/WordCount.jar")
.withMainClass("com.my.Main1") // optional main class, this can be omitted if jar above has a manifest
.withArgs("--verbose"); // optional list of arguments
StepConfig customStep = new StepConfig("Step1", hadoopConfig1);
AddJobFlowStepsResult result = client.addJobFlowSteps(new AddJobFlowStepsRequest()
.withJobFlowRole("jobflow_role")
.withServiceRole("service_role")
.withSteps(hive, customStep));
System.out.println(result.getStepIds());
}
}
What could be the reason that the code is not running ?
Are there any tutorials based on the latest version ?
