I am using spring-cloud-stream-binder-kafka-1.1.1.RELEASE.jar to implement Kafka in Spring Boot application.
java.net.ConnectException: Connection refused

Is this issue resolved?

I am trying to index Maven Repositories in IntelliJ so I can search for classes, but I get an error every time. I am using the latest version of IntelliJ. Why am I unable to update them?
This is what appears in the logs

Are you in a secured cluster (acces via https)? If so you need to give access to your nodes, like so (within the registry) :
If you are not in a secure cluster, try so set up an adresse like that : http://hostname:port . Without adding /nifi-registry
Another way to look, is within docker, be sure that your host can communicate with each others (Easier to be on the same docker network, and try to ping eachother)
I need to send spans through RabbitMQ to Zipkin. I'm Using Spring-Cloud-Sleuth Edgware-SR5 version and SpringBoot 1.5.3.RELEASE versions.
With older Spring-cloud sleuth version (spring-cloud-stream-binder-rabbit - v1.1.4.RELEASE) it was working fine.
When I try to start the service, I'm getting " "AsyncReporter{RabbitMQSender{addresses=[localhost:5672], queue=zipkin}}. Unable to establish connection to RabbitMQ server" error.
I have gone through the documentations, but I could't able to resolve this issue.

Simply means that RabbitMQ is not running on localhost:5672 (which is the default if you don't provide a host/port, or addresses, for it in your application.yml).
I have a job that get messages from an on-premise kafka and send it to BigQuery using Dataproc. But sometimes I get both bellow exceptions that causes my job to fail.

I checked the items listed in http://wiki.apache.org/hadoop/ConnectionRefused.
On the exception, we can see that:
"Call From worker-3/ip to worker-1:50267"
Communication between workers on a unknown port (?) (50267)
And sometimes with:
"Call From master-node/ip to master-node:8020"
Communication in master on NameNode metadata service port (8020).
On another reference https://serverfault.com/questions/725262/what-causes-the-connection-refused-message, it says:
The message 'Connection Refused' has two main causes:
Nothing is listening on the IP:Port you are trying to connect to.
The port is blocked by a firewall.
Shouldn't this be handled by Dataproc?

My thoughts are that both errors are pretty generic and happened inside the Dataproc cluster, not related to my application. Am I correct? I'm using a retry aproach to resolve my problem right now. But I would like to understand why these errors occur in a Hadoop-based product like Dataproc and if I have a way to avoid them? Shouldn't Dataproc take care of all of it for the users?

how to resolve this exception
Please give me any clue
Please, upgrade to more actual Spring Integration version. The issue for property place holder has been fixed.
From other side there is a cause, which indicates a reason of the MessageHandlingException.
So, take a look to it or just share a StackTrace here and we'll try to help you.
