Hi, I am grad student, and I am working on Storm as a part of my course project.
I have cloned the source code from git, and followed the instructions. I am using branch : 0.10.0 After "mvn package", when I copy the apache-storm-<version>.tar.gz in my home, untar it and try to run nimbus. I get error: Exception in thread "main" java.lang.ExceptionInInitializerError at org.apache.storm.utils.ConfigUtils.readStormConfigImpl(ConfigUtils.java:138) at org.apache.storm.utils.ConfigUtils.readStormConfig(ConfigUtils.java:134) at org.apache.storm.command.ConfigValue.main(ConfigValue.java:27) Caused by: java.lang.RuntimeException: java.io.IOException: Found multiple storm.yaml resources. You're probably bundling the Storm jars with your topology jar. [jar:file:/home/vgoyal5/apache-storm-2.0.0-SNAPSHOT/lib/storm-core-2.0.0-SNAPSHOT.jar!/storm.yaml, file:/home/vgoyal5/apache-storm-2.0.0-SNAPSHOT/conf/storm.yaml] at org.apache.storm.utils.Utils.findAndReadConfigFile(Utils.java:372) at org.apache.storm.utils.Utils.readStormConfig(Utils.java:456) at org.apache.storm.utils.Utils.<clinit>(Utils.java:173) ... 3 more I deleted the "/home/vgoyal5/apache-storm-2.0.0-SNAPSHOT/conf/storm.yaml" file and again tried. This time I was able to connect the nimbus and supervisors and could see the connections in UI. As soon as I tried to submit the topology with the command: storm jar examples/storm-starter/target/storm-starter-2.0.0-SNAPSHOT.jar org.apache.storm.starter.ExclamationTopology exclamation-topology I got error: org.apache.storm.utils.NimbusLeaderNotFoundException: Could not find leader nimbus from seed hosts [sp16-cs525-g05-01.cs.illinois.edu]. Did you specify a valid list of nimbus hosts for config nimbus.seeds? First ,I am not able to resolve this error, and second, I cannot make changes in storm.yaml as I deleted the conf/storm.yaml I am a beginner in Storm. I have been trying this for a day now. Any help would be appreciated!! Thanks! Vibha Goyal
