If you are going to access jars outside HDFS you must have their path
listed in livy.file.local-dir-whitelist like you found.

Subject: Re: ClassNotFoundException on job submit
Ok I am getting somewhere:
@RunWith(JUnit4.class)
public class LivyTestCase {
private static final int SAMPLES = 10000;
private static final String LIVY_URI = "
https://urldefense.proofpoint.com/v2/url?u=http-3A__spark-2Dmaster-3A8998&d=DwIBaQ&c=jf_iaSHvJObTbx-siA1ZOg&r=S1_S7Dymu4ZL6g7L21O78VQZ53vEnAyZ-cx37DPYDyo&m=m06yDfiPVPYT_h4awyPxVA7SKfA9V1MlTzp3mQ8REcE&s=v2g-MD9i6gEg80s1fyGAzLe9WCOhelMfEygM1WOwNeM&e=
";
@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?

when starting their
# sessions.
