Re: ClassNotFoundException on job submit

2017-10-26 Thread Stefan Miklosovic 
Ok I am getting somewhere:

@RunWith(JUnit4.class)
public class LivyTestCase {

private static final int SAMPLES = 1;

private static final String LIVY_URI = "http://spark-master:8998;;

@Rule
public TemporaryFolder jarFolder = new TemporaryFolder();

@Test
public void testPiJob() throws Exception {

File jarFile = jarFolder.newFile("testpijob2.jar");

ShrinkWrap.create(JavaArchive.class)
.addClass(PiJob.class)
.as(ZipExporter.class)
.exportTo(jarFile, true);

LivyClient client = new LivyClientBuilder()
.setURI(new URI(LIVY_URI))
.build();

System.out.println("Uploading PiJob jar");

client.uploadJar(jarFile).get();

System.out.println("PiJob jar uploaded");

final Double result = client.submit(new PiJob(1000)).get();

System.out.println(result);
}
}

But while doing so, it gives me:

java.util.concurrent.ExecutionException: java.io.IOException:
Bad Request: "requirement failed: Local path
/root/.livy-sessions/c7dbb697-13ed-443f-a630-bc9d9a544f6b/testpijob2.jar

I have checked that there is nothing else but that PiJob.class in that
JAR. Nothing else at all.

I have a feeling that the path for that jar needs to be visible to all
slaves, I do not have HDFS, I have spark slaves in Docker containers
so once I want to upload it, I see it in spark master
/root/.livy-sessions, but it is not in containers ...

Could not this be helpful?

I think I have to add a jar with PiJob on the classpath of Livy so it
knows how to deserialize it  hm

Re: ClassNotFoundException on job submit

2017-10-26 Thread Stefan Miklosovic 
I have did it as you suggested and it seems to start the jobs OK and I
see the sessions in UI but while it is being computed (I see the job
is distributed on two spark slaves where in front of that there is
spark-master), I am computing this from my localhost:

@RunWith(JUnit4.class)
public class LivyTestCase {

private static final int SAMPLES = 1;

private static final String LIVY_URI = "http://spark-master:8998;;

@Test
public void testPiJob() throws Exception {

LivyClient client = new LivyClientBuilder()
.setURI(new URI(LIVY_URI))
.build();

final Double result = client.submit(new PiJob(1000)).get();

System.out.println(result);
}
}

It is a PiJob from sites examples.

Now what I see in Livy logs is this

I know to read it - I understand there is not PiJob on the class path,
but why? I have just sent that class to Livy ...

Re: ClassNotFoundException on job submit

2017-10-26 Thread Saisai Shao 
You can choose to set "livy.spark.master" to "local" and
"livy.spark.deploy-mode" to "client" to start Spark with local mode, in
such case YARN is not required.

Otherwise if you plan to run on YARN, you have to install Hadoop and
configure HADOOP_CONF_DIR in livy-env.sh.
