Hey all, I've downloaded the HDF Sandbox (3.1) with an VirtualBox Image. After I imported the VM with the default settings i started up the VM and started the Tutorial describt in (https://de.hortonworks.com/tutorial/real-time-event-processing-in-nifi-sam-schema-registry-and-superset/) After the login into the Ambaria Webinterface (Port 8080) no Services were startet, so i stated all services on my own. In Chapter 2. (Real-Time Event Processing In NiFi, SAM, Schema Registry and SuperSet) in Step 3 i am not able to deploy the Trucking-IoT_Demo instead i got the following error message: Topology submission failed due to: java.lang.Exception: Topology could not be deployed successfully: storm deploy command failed with Exception in thread "main" java.lang.RuntimeException: org.eclipse.aether.resolution.DependencyResolutionException: Failed to read artifact descriptor for org.apache.kafka:kafka-clients:jar:0.10.2.1, Caused by: org.eclipse.aether.resolution.DependencyResolutionException: Failed to read artifact descriptor for org.apache.kafka:kafka-clients:jar:0.10.2.1, Caused by: org.eclipse.aether.collection.DependencyCollectionException: Failed to read artifact descriptor for org.apache.kafka:kafka-clients:jar:0.10.2.1, Caused by: org.eclipse.aether.resolution.ArtifactDescriptorException: Failed to read artifact descriptor for org.apache.kafka:kafka-clients:jar:0.10.2.1, Caused by: org.eclipse.aether.resolution.ArtifactResolutionException: Could not transfer artifact org.apache.kafka:kafka-clients:pom:0.10.2.1 from/to central (http://repo1.maven.org/maven2/): Connect to repo1.maven.org:80 timed out, Caused by: org.eclipse.aether.transfer.ArtifactTransferException: Could not transfer artifact org.apache.kafka:kafka-clients:pom:0.10.2.1 from/to central (http://repo1.maven.org/maven2/): Connect to repo1.maven.org:80 timed out, Caused by: org.apache.http.conn.ConnectTimeoutException: Connect to repo1.maven.org:80 timed out I hope you can help me 🙂 kind regards Andreas
