I connect my app to Kafka through SASL_SSL using keytab. At first it worked well, but once it got an error. How to fix this and avoid such errors in future? stacktrace is bellow.

I am trying to replicate data from Kafka topic to apache ignite cluster. I have added ignite-core.jar along with all other required files in plugins and it's loaded in connector as per the logs. Still I'm facing this error. Any suggestions would be helpful. Thank you.

It looks like you have ignite-kafka module in your classpath, but not ignite-core and its dependencies, which is also needed. My understanding ends there.
I have a Flink cluster running on minikube : 1 jobmanager and 3 taskmanagers.
I am using Kubernetes Ha service to handle jobmanager leader election.
when i am trying to kill the jobmanager to simulate a crash , the taskmanager could not connect
the new jobmanager it try always to connect the previous ip address of the jobmanager that was terminated.
here is the exception :

I am trying to run keycloak on kubernetes so I follow this example on my kubernetes cluster. But when I run command:
kubectl create -f https://raw.githubusercontent.com/keycloak/keycloak-quickstarts/latest/kubernetes-examples/keycloak.yaml
I got database error after 2 minutes. Why I can not run this simple example without error ?

00:17:39,573 FATAL [org.keycloak.services] (ServerService Thread Pool -- 66) Error during startup: java.lang.RuntimeException: Failed to connect to database
your error is clearly informing keylock is trying to connect with the database but can't get it there might be an issue with your configuration file or environment you are passing.
You can try this out : https://github.com/harsh4870/Keycloack-postgres-kubernetes-deployment
let me know if these files don't work. it's not for a production use case but you can use it for setting up the dev environment.

I am using jBPM 7.3. Everything works fine while starting but after around 5 minutes it tries to connect to 127.0.0.1:9990 port. Yet I have specified my IP address while starting as ./standalone.sh -b 10.14.24.161.
Even I changed it in standalone.xml but it is still trying to connect with localhost IP. The error I am getting is the following:

Configure the following parameters in the datasource-management.properties file located in the /WEB-INF/classes/ directory of your KieWorkbench distribution file.
e.g. in kie-wb-7.0.0.Final-wildfly10.war
datasource.management.wildfly.host=<your_hostname_or_ip>
datasource.management.wildfly.port=<your_port>
datasource.management.wildfly.admin=<your_admin_user>
datasource.management.wildfly.password=<your_admin_password>
datasource.management.wildfly.realm=ApplicationRealm
Thanks to Walter Medvedeo, who came up with this solution.
I have added following argument in start script(build.xml). And it seems to solved the error.
<arg value="-Dorg.uberfire.ext.security.management.wildfly.cli.port=<changed_port>"/>
my port was offsetted by 150 so I used 10140
