Iam using bluemix message hub service in my node app which is in production.Now we have run in to an issue that message hub service goes down everyday and the app needs to be restarted then.This cant be done so.
We are getting the following logs
2016-10-16T17:41:42.66+0100 [App/0] OUT Unable to consume topic: Error: Request returned
status code 404 but it was not in the accepted list. The REST API responded with the
following message: Consumer instance not found.
2016-10-16T17:41:46.66+0100 [App/0] OUT got error: { [Error: Request returned status code
404 but it was not in the accepted list. The REST API responded with the following message:
Consumer instance not found.] statusCode: 404, errorCode: 40403 }
Is there any way that we can handle this.This is failing over here
run: function(callback) {
var that = this;
consumerInstance.get(topic)
.then(function(data) {
that.consume(data);
return callback();
})
.fail(function(error) {
console.log("got error: ", error);
return callback(error);
})
}
This is the code which we are using for reference
https://github.com/ibm-cds-labs/Spark-Twitter-Watson-Dashboard/blob/master/server/messageHubBridge.js?s_tact=C43301PW
Any thoughts on how to resolve this issue.
Thanks,
Harish.
Hi the REST endpoint for MessageHub gets recycled every 24 hours.
Clients are expected to handle this by creating a new consumer instance.
HTH,
Edo
As per the Message Hub documentation, the REST service restarts daily. After the REST API has restarted, you will have to recreate your Kafka consumer instances.
Thanks,
Simon.

I am trying to build a very simple RabbitMQ-FastAPI based application that would be able to run on Kubernetes. Created two separate APIs for producer and consumer.
Producer API:
#app.get("/hello/{message}")
def post_message(message: str = Body(..., example="Hello World!")):
try:
connection = pika.BlockingConnection(
pika.ConnectionParameters(host="rabbitmq-0.rabbitmq-headless.keda.svc.cluster.local", port=5672,
credentials=pika.PlainCredentials("user", "PASSWORD")))
channel = connection.channel()
#channel.exchange_declare(exchange='logs', exchange_type='direct')
#severity = ['hello', 'message', 'error']
#messages = ['Hafizur', 'message', 'error']
channel.queue_declare(queue='hello')
channel.basic_publish(exchange='', routing_key='hello', body=message)
connection.close()
return {"Successfully sended {} do queue".format(message)}
Consumer API:
#app.post("/message")
def get_message():
try:
connection = pika.BlockingConnection(
pika.ConnectionParameters(host="rabbitmq-0.rabbitmq-headless.keda.svc.cluster.local", port=5672,
credentials=pika.PlainCredentials("user", "PASSWORD")))
channel = connection.channel()
channel.queue_declare(queue='hello')
channel.basic_consume(on_message_callback=callback, queue="hello", auto_ack=True)
print(" [*] Waiting for messages. To exit press CTRL+C")
channel.start_consuming()
except Exception as e:
raise HTTPException(status_code=500, detail=str(e))
From here I am building two docker images, one for the producer and another for the consumer. Using those built two deployments on K8S. Did port forwarding and accessed to the producer API and tried to send some message to RabbitMQ queue. But getting Error: Unprocessable Entity.
I am seeking your help to solve this issue.
I have 2 requirements:
1:I have a clusterID. I need to start the cluster from a "Wb Activity" in ADF. The activity parameters look like this:
url:https://XXXX..azuredatabricks.net/api/2.0/clusters/start
body: {"cluster_id":"0311-004310-cars577"}
Authentication: Azure Key Vault Client Certificate
Upon running this activity I am encountering with below error:
"errorCode": "2108",
"message": "Error calling the endpoint
'https://xxxxx.azuredatabricks.net/api/2.0/clusters/start'. Response status code: ''. More
details:Exception message: 'Cannot find the requested object.\r\n'.\r\nNo response from the
endpoint. Possible causes: network connectivity, DNS failure, server certificate validation or
timeout.",
"failureType": "UserError",
"target": "GetADBToken",
"GetADBToken" is my activity name.
The above security mechanism is working for other Databricks related activity such a running jar which is already installed on my databricks cluster.
2: I want to create a new cluster with the below settings:
url:https://XXXX..azuredatabricks.net/api/2.0/clusters/create
body:{
"cluster_name": "my-cluster",
"spark_version": "5.3.x-scala2.11",
"node_type_id": "i3.xlarge",
"spark_conf": {
"spark.speculation": true
},
"num_workers": 2
}
Upon calling this api, if a cluster creation is successful I would like to capture the cluster id in the next activity.
So what would be the output of the above activity and how can I access them in an immediate ADF activity?
For #2 ) Can you please check if you change the version
"spark_version": "5.3.x-scala2.11"
to
"spark_version": "6.4.x-scala2.11"
if that helps
When I watch the certain ids in the collection using MongoDB watch I am getting error
ERROR Error: Uncaught (in promise): e: (TRANSPORT_ERROR): the request transport encountered an error communicating with Stitch: event source failed to open and will not reconnect; check network log for more details
e: (TRANSPORT_ERROR): the request transport encountered an error communicating with Stitch: event source failed to open and will not reconnect; check network log for more details
It was working till yesterday it started from today
const db = mongoClient.db(environment.databaseName);
const comments = db.collection('collectionName');
this.changeStream = await comments.watch(ids);
this.changeStream.onNext((event) => {
console.log('Watched document changed:', event);
this.fetchData();
});
I expect that whenever the document is changed in the list of ids. Change event should trigger.
This indicates that your app is unable to communicate with the stitch backend, probably because of not internet or poor network
I'm trying to deploy my release on a azure web App. It's not working and I don't know what to do. Maybe I'm missing something in the configuration in my app service or in my release pipeline. I've got the following error

And here is a block of my debug :

And some screenshot of
azure missing configuration ?
release pipeline config 1
release pipeline config 2
release pipeline config 3
Let me know if you need more informations.. I'm new in this so maybe missing simple things... Best regards
do you have setting identity Status On ?
like below
In my case, we had just moved our app service to a new resource group, but the pipeline was still referencing the old resource group. Correcting the resource group fixed the issue
A simple typo can also be the reason for this error message.
You will get this error message even though if it's just a typo or wrong value in your "slotName".
Please do ensure that the "slotName" you've given is the actual slotname (the default is 'production'). So if you've added a slot that's called 'stage' then inside the portal it will have your '/stage' or '-stage', but it's still just called 'stage'.
I know several have had this error message shown and none of the above helped them out (I faced the same issue the first time).
My research indicated this to be an intermittent problem.
I redeployed 2 times and it worked.
The first redeploy - just seemed to wait for ages to connect to an available agent, so I cancelled that too, and redeployed - which worked without any issue.
If this is still an issue or if someone had this issue, all I did was just to rerun the release and it well went well. Hopefully someone has saved time by just re-releasing, if this wont work then probably try something else.
I am trying to run REST API from Load Runner but unable to do it. Every times its throws below exception
Action.c(4): Error -26612: HTTP Status-Code=500 (Internal Server Error) for "http://ipaddress/LoyaltyApi/api1/loyaltycard/linkcard", Snapshot Info [MSH 1 1] [MsgId: MERR-26612]

}
I have tested the same URL with POST parameter in POSTMAN and it's working fine without any issue.
I am very new in this technology so unable to solved the issue. Please help.
I am very new in this technology....
Assuming your management has moved you to this role, have they provided you with training on the tool and a mentor for a period of time. If not they have set you up for failure.
