Zookeeper -Kafka: ConnectException - Connection refused - amazon-web-services

I am trying to setup 3 Kafka brokers on ubuntu EC2 machines. But I am getting ConnectException while starting zookeeper. All the ports in the security group of my ec2 intsances are already open.
Below is the stack trace:

I have added server's public IP in /etc/hosts of the instances. My modified /etc/hosts is as:
127.0.0.1 localhost localhost.localdomain ip-10-131-X-217
127.0.0.1 localhost localhost.localdomain 52.37.XX.70
127.0.0.1 localhost
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
The unique myid entries in /tmp/zookeper/myid are also entered correctly.
I have followed all the steps mentioned in: How to create a MultiNode - MultiBroker Cluster for Kafka on AWS

The issue was because I was using the Public IP of the server. Instead of that, use of Public DNS of ec2 instances fixed the issue.

I check for security groups as instructed in post link. I made the RDS publicly accessible and allowed access from all IP's and all protocols in the security group. Both my RDS and ECS are in same VPC and same security group. I am not really sure what else to do here ? Will there be an issue connecting since its a docker container ?
I made the RDS publicly accessible
That could actually be a problem. The ECS task may be resolving the RDS endpoint to an Internet IP address, and then trying to connect to the database over the Internet, instead of keeping the traffic inside the VPC. If the ECS task doesn't have a public IP address, or it isn't running in a subnet with a route to a NAT gateway, then it wouldn't be able to connect.
Both my RDS and ECS are in same VPC and same security group.
Being in the same security group does not confer any connectivity by default. This is actually bad practice because it doesn't allow you to restrict traffic on specific ports, since you are mixing different services that use different ports in the same security group. Since you allowed access from all IPs and protocols this shouldn't be the cause of your current issue however.
Some steps to debug this would be to use ECS Exec, or spin up an EC2 instance in the same VPC subnet (with the same security group), and see if the RDS endpoint resolves to an internal or external IP, and see if you can connect with the MySQL command line.

JHipster project deployed using aws sub-generator returns http 404 error

This question about "aws sub-generator" (not "aws-containers sub-generator").
Question 1:
Is this generator supposed to update "application-prod.yml"? I can see the information I provided while running the sub-generator including the database name in ".yo-rc.json". But database user-name and password are neither there nor in the "application-prod.yml".
Question 2:
I generated a simple JHipster project with some entities. It was working fine locally on my PC. I used the "aws sub-generator" and everything went well. It created the Elastic Beanstalk application, an EC2 instance, the S3 bucket, the RDS database, the security groups...Here is the event log of the Elastic Beanstalk:

The JHipster AWS ElasticBeanstalk option only works with monoliths and won't deploy the JHipster Registry if that option is chosen when generating the project.
If you want to disable the JHipster Registry feature, you can set two config variables in your project. In bootstrap-prod.yml, set spring.cloud.config.enabled: false and disable Eureka in application-prod.yml with eureka.client.enabled: false.
In regards to the database connection settings, those are set as environment variables when creating the ElasticBeanstalk environment which Spring Boot uses instead of the hardcoded config in application-prod.yml

Neo4j HA Cluster Error connecting to graph database using Bolt

We are using neo4j-enterprise-3.0.4 in cluster on AWS with bolt protocol. HAproxy is used to we know who is master and who are the slaves in the HA cluster. The Java application is using the spring-data-neo4j framework and is deployed on a Tomcat 7.
Structure on AWS is: Neo4j HA Cluster (1 master and 2 slaves) ---> HAproxy ----> ELB
We are receiving this error. An error does not occur every time but occasionally
(yesterday 3 times).

We can not figure out where is a problem. Is it problem in:
1) org.neo4j.ogm.drivers.bolt.driver.BoltDriver
2) ELB on AWS
3) HAproxy .cfg
4) Bolt protocol on AWS
Before we were using Bolt as protocol, we used the HTTP endpoint, with the same settings on AWS and we did not had problem.
EDIT
We change configuration so this is what we know about our questions:
1) org.neo4j.ogm.drivers.bolt.driver.BoltDriver - error is only appear here on Tomcat 7.
2) ELB on AWS - we not using ELB any more we are connecting directly to HAproxy
3) HAproxy .cfg - our PHP team using port 83 to connect to Neo4j HA Cluster using http protocol and they do not have errors.
4) Bolt protocol on AWS - we add logs on ELB and EC2 and we did not receive any error about Bolt protocol.
Is there a problem with neo4j-enterprise-3.0.4 and neo4j-ogm-bolt-driver 2.0.4?
EDIT
There is a issue between neo4j-enterprise-3.0.4 or neo4j-ogm-bolt-driver 2.0.4 and AWS ELB or both.
We change our app settings and we are using Http driver with same structure on AWS instead of Bolt driver. We did not receive error.
We did not find a way to fix this issue.

connection issue with hazelcast on amazon AWS

I am using Hazelcast v3.6 on two amazon AWS virtual machines (not using the AWS specific settings for hazelcast). The connection is supposed to work via TCP/IP connection settings (not multicasting). I have opened 5701-5801 address for connection on the virtual machines.
I have tried using iperf on the two virtual machines using which I can see that the client on one VM connects to the server on another VM (and vice versa when I switch the client server setup for iperf).
When I launch two Hazelcast servers on different VM's, the connection is not established. The log statements and the hazelcast.xml config are given below (I am not using the programmatic settings for Hazelcast). I have changed the IP addresses below:

Note:
I forgot to mention that I can connect from hazelcast client to server i.e. when I use a hazelcast client to connect to a single hazlecast server node, I am able to connect just fine
An outbound ports range which includes 0 is interpreted by hazelcast as "use ephemeral ports", so the <outbound-ports> element has actually no effect in your configuration. There is an associated test in hazelcast sources: https://github.com/hazelcast/hazelcast/blob/75251c4f01d131a9624fc3d0c4190de5cdf7d93a/hazelcast/src/test/java/com/hazelcast/nio/NodeIOServiceTest.java#L60

Soap WS Connection refused

I'm trying to connect to a SOAP webserver, I was given a certificate but I get the below exception.
I did:
$openssl pkcs12 -in cert.pfx -out certificate.cer -nodes
$keytool -import -alias webserver -file certificate.cer
Certificate was added to keystore
I have a junit test that calls the remote server with these JVM options:
-ea -Djavax.net.debug=all -Dcom.sun.xml.ws.transport.http.client.HttpTransportPipe.dump=true
-Dcom.sun.xml.internal.ws.transport.http.client.HttpTransportPipe.dump=true
-Dcom.sun.xml.ws.transport.http.HttpAdapter.dump=true
-Dcom.sun.xml.internal.ws.transport.http.HttpAdapter.dump=true
-Djavax.net.ssl.trustStore=certificate.cer
-Djavax.net.ssl.trustStoreType=PEM
-Djavax.net.ssl.trustStorePassword=pwd
-Djavax.net.ssl.keyStore=certificate.cer
-Djavax.net.ssl.keyStoreType=PEM
-Djavax.net.ssl.keyStorePassword=pwd
the remote call is done using:
authenticationService.getAuthenticationServiceSoap().authenticateWithPasswordAuth(clientId, username, password);
where the client I'm using has got these annotations:
#WebServiceClient
public class AuthenticationService extends Service {
and
#WebEndpoint(name = "AuthenticationServiceSoap")
public AuthenticationServiceSoap getAuthenticationServiceSoap()
I don't do anything else code wise, and I get the below Exception:
I don't even understand if java is trying to use https or no.
