how to deal with java.net.UnknownHostException: kubernetes.default.svc when using fabric8io? - kubernetes

I was using fabric8io to write a service function, relevant code is as below
KubernetesClient fabricClient = new DefaultKubernetesClient();
fabricClient.pods().inNamespace("xxxnamespace").withLabel("somekey", somevalue).list().getItems()
It was working fine when I'm doing unit test.
But when I was deploying the whole application, and trigger the service funtion, it throws an error as below

in which DTSServiceImplis my service implementation class.
On the deployment machine, I was putting kubeconfig file on ~/.kube/config, and kubectlcommand line is woking fine.
I have no clue how to handle this problem. Any idea how should I find out the exception reason？
Thanks in advance!


Fabric8 uses Kubernetes REST API to perform their operations, by default their HTTP client is assuming that it's running inside kubernetes cluster which is why it's trying to reach kubernetes.default.svc
Since you're calling it outside the cluster then you must tell Fabric8 the address of your cluster, this can be done by specifying the host during creation of the client
new DefaultKubernetesClient("https://my-cluster");
If you're able to SSH to the server which is running your application and ping the cluster address, most likely fabric8 will work.


Thanks to #Yayotron and my colleagues, it turns out that I was setting the wrong path to kubeconfig system property.
According to this question, I was setting kubeconfig system property to some specific path, so that fabric8 client can get the kubeconfig file from that path and get clusters informations / authentication tokens, etc.
So if anyone meet this exception in the future, you can consider whether if the client configuration has been configured right.

org.springframework.messaging.MessageDeliveryException: Dispatcher has no subscribers for channel- occures before subscriber bean is created

I am trying to implement ReplyingKafkaTemplate with spring batch integration.
It is actually running eagerly and throwing the "Dispatcher has no subscribers for channel" error before the subscriber bean is created. As you can see in the log.
org.springframework.messaging.MessageDeliveryException: Dispatcher has no subscribers for channel 'kafka Cloud Task.gatewayinputchannel'.;
Adding {kafka:outbound-gateway:kafkaConfig.outGateway.serviceActivator} as a subscriber to the 'gatewayinputchannel' channel
2022-08-18 02:02:08.068 INFO 24232 --- [ main] o.s.integration.channel.DirectChannel : Channel 'kafka Cloud Task.gatewayinputchannel' has 1 subscriber(s).
2022-08-18 02:02:08.068 INFO 24232 --- [ main] o.s.i.endpoint.EventDrivenConsumer : started bean 'kafkaConfig.outGateway.serviceActivator'
Is there a way to prevent it from running eagerly? and wait till all the beans are created.
My ReplyingKafkaTemplate is described as below.
#Bean
#ServiceActivator(inputChannel = "gatewayinputchannel")
public KafkaProducerMessageHandler<String, Message<?>> outGateway(
ReplyingKafkaTemplate<String, Message<?>, Message<?>> kafkaTemplate) {
KafkaProducerMessageHandler<String,Message<?>> kpmh = new KafkaProducerMessageHandler<String,Message<?>>(kafkaTemplate);
kpmh.setMessageKeyExpression(new LiteralExpression(kafka_processing_topic));
kpmh.setTopicExpression(new LiteralExpression(kafka_processing_topic));
kpmh.setOutputChannel(gatewayoutputchannel());
return kpmh;
}
Edited
#Configuration
#MessagingGateway
#EnableIntegration
#IntegrationComponentScan
public interface IntegrationGateway {
#Gateway(requestChannel = "gatewayinputchannel", replyChannel = "gatewayoutputchannel")
public Message<?> sendToKafka(Message<?> input);
}
We are calling it from the item processor of a batch job
Message<?> request= MessageBuilder.withPayload(inpMessage).copyHeaders(header).build();
Message<?> response = integrationGateway.sendToKafka(request);
-------------------------- Edit 3 --------------------------
How you start the batch job ? :
We are trying to start the batch job from a spring boot project with #Scheduled method programmatically using JobLuncher.
I have below flag to prevent the job starting automatically.

It is not a problem of this outGateway bean and its gatewayinputchannel subscription. It is a problem of producer which sends to this gatewayinputchannel too early. So, share with us, please, what and how does that instead.

spark-shell not working on installing apache spark. Error: system cannot find the path specified

I installed Apache Spark, have java and python installed as well. Set up the environment variables as per this article: https://phoenixnap.com/kb/install-spark-on-windows-10
I have also installed winutils.exe.
Initially I was getting an error like :
missing Python executable
defaulting to 'C:\spark\bin..' for SPARK_HOME environment variable.
Please install Python or specify the correct Python executable in PYSPARK_DRIVER_PYTHO
N or PYSPARK_PYTHON environment variable to detect SPARK_HOME safely. To fix this i added a environment variable
Name: PYSPARK_DRIVER_PYTHON
value: C:\Program Files\Python310
Now, on the terminal, C:\spark\bin>spark-shell gives the following output:
The system cannot find the path specified.
The system cannot find the path specified.

How do I fix this?

I think there is issue with your computer name , that contains string and spark libs/scripts not able to understand the same.
spark://DESKTOP-E76IK3L:52769/
can you change your computer/Laptop name to any string(no number, colons in between)
something like : MyDesktop
and try running spark-shell

Java parallelStream run task always wait a long time, why?

I use parallelStream to execute backgroud task in Spring #Async annotation. but the task always blocked then stop. the core code is:
#Async
public void task() {
List<ConfigSymbol> symbols = SymbolUtils.getSaasOpenSymbol();
symbols .parallelStream().forEach(symbol->{
//execute task. 1 minute per loop
}
}
I catch the thread stack to diagnosis the problem. but can not find reason.
why the ForkJoinTask status is waiting .
"SimpleAsyncTaskExecutor-1609" #1777 prio=5 os_prio=0 tid=0x00007fb968006800 nid=0x6f5 in Object.wait() [0x00007fba2d119000]
