Hi, Apologies if this is a wrong thread to post to, but I have a Kylin question that I couldn't resolve myself yet.
I am deploying Kylin on AWS EMR by following the official tutorial http://kylin.apache.org/docs/install/kylin_aws_emr.html I am interested in running Near RT Streaming using Kafka. My Kafka is deployed on AWS MSK. I managed to deploy Kylin, connect it with Kafka stream and configure model and the cube, however, I have a problem enabling the cube to run OLAP. When I execute: ./bin/kylin.sh streaming start I am getting this error message in the streaming logs: 2020-07-24T15:58:12,763 ERROR [main] org.apache.kylin.stream.server.StreamingReceiver - streaming receiver start fail java.io.IOException: Failed to bind to 0.0.0.0/0.0.0.0:9090 at org.eclipse.jetty.server.ServerConnector.openAcceptChannel(ServerConnector.java:346) ~[kylin-stream-receiver-3.1.0-all.jar:3.1.0] at org.eclipse.jetty.server.ServerConnector.open(ServerConnector.java:307) ~[kylin-stream-receiver-3.1.0-all.jar:3.1.0] at org.eclipse.jetty.server.AbstractNetworkConnector.doStart(AbstractNetworkConnector.java:80) ~[kylin-stream-receiver-3.1.0-all.jar:3.1.0] at org.eclipse.jetty.server.ServerConnector.doStart(ServerConnector.java:231) ~[kylin-stream-receiver-3.1.0-all.jar:3.1.0] at org.eclipse.jetty.util.component.AbstractLifeCycle.start(AbstractLifeCycle.java:72) ~[kylin-stream-receiver-3.1.0-all.jar:3.1.0] at org.eclipse.jetty.server.Server.doStart(Server.java:385) ~[kylin-stream-receiver-3.1.0-all.jar:3.1.0] at org.eclipse.jetty.util.component.AbstractLifeCycle.start(AbstractLifeCycle.java:72) ~[kylin-stream-receiver-3.1.0-all.jar:3.1.0] at org.apache.kylin.stream.server.StreamingReceiver.startHttpServer(StreamingReceiver.java:94) ~[kylin-stream-receiver-3.1.0-all.jar:3.1.0] at org.apache.kylin.stream.server.StreamingReceiver.start(StreamingReceiver.java:63) ~[kylin-stream-receiver-3.1.0-all.jar:3.1.0] at org.apache.kylin.stream.server.StreamingReceiver.main(StreamingReceiver.java:51) [kylin-stream-receiver-3.1.0-all.jar:3.1.0] Caused by: java.net.BindException: Address already in use at sun.nio.ch.Net.bind0(Native Method) ~[?:1.8.0_252] at sun.nio.ch.Net.bind(Net.java:433) ~[?:1.8.0_252] at sun.nio.ch.Net.bind(Net.java:425) ~[?:1.8.0_252] at sun.nio.ch.ServerSocketChannelImpl.bind(ServerSocketChannelImpl.java:220) ~[?:1.8.0_252] at sun.nio.ch.ServerSocketAdaptor.bind(ServerSocketAdaptor.java:85) ~[?:1.8.0_252] at org.eclipse.jetty.server.ServerConnector.openAcceptChannel(ServerConnector.java:342) ~[kylin-stream-receiver-3.1.0-all.jar:3.1.0] ... 9 more This is strange because there is no receiver running and no process is using port 9090. What else should I check? Did I miss some configuration? Thanks & best regards, Kirill
