Apache Storm: Nimbus not starting on Port 6627

I can't see anything on port 6627 after starting Nimbus. I am getting the Connection Refused error. Following errors are thrown in Nimbus Log:

6899 [main] ERROR com.smarterme.intake.EmbeddedTopologyRunner - Toplogy submitting failed.....org.apache.thrift7.transport.TTransportException: java.net.ConnectException: Connection refused
java.lang.RuntimeException: org.apache.thrift7.transport.TTransportException: java.net.ConnectException: Connection refused
at backtype.storm.utils.NimbusClient.getConfiguredClient(NimbusClient.java:38)
at backtype.storm.StormSubmitter.submitTopology(StormSubmitter.java:116)**


Do you guys have any idea about this?

Answer

Add "nimbus" to /etc/hosts file as alias to 127.0.0.1 and localhost.

Make sure iptables is not the issue from the host you are trying to run or Most likely there is something wrong in your ~/.storm/storm.yaml
