Apache Ignite: Slow Node join and failure

We have a Ignite setup with 3 Servers and Persistence and therefore Baselining enabled. From time to time we have the issue that the Servers take a long time to rebuild the cluster after all Nodes are restarted. Ignite runs embedded in the application.

... it continues like that till the join or failure
The logs log the same on all servers. In this case server 1 and 2 create a cluster after 7 minutes. server 3 fails after 9 minutes due to incompatible baseline topology. After reseting the failed server it can rejoin the cluster. The behavior only happens sometimes. Most of the time the servers rebuild the cluster without problem.

Connect to an azure iot hub from inside a kubernetes cluster via amqp over websockets

we are trying to communicate to an azure iothub via amqp over websocket from a java docker container inside an azure kubernetes cluster. Sadly it seems, that the container cant establish a connection while locally or even on another virtual machine (where only docker is installed) the container run successfully.
The network policies rules should allow all necessary protocols and ports to communicate with eventhub endpoint of the iot hub.
Does anybody know which switch we have to pull to "allow" the container from the cluster the communication with the iothub?
The only logs we have are this:

The failure was not the networking at all.
My mistake was, that i assume if i can run the container manual via docker run -it * it should also work in a kubernetes cluster. But with the -it argument the container stays open und and pseudo-tty was attached. But in the kubernetes cluster this of cause will not happen, so we have to adjust the loop logic of the java application and it works after.
Thanks # all

Riak java client, execute() never returns

I've setup a riak server on ubuntu.
http://192.168.0.102:8098/ping return "OK"
I'm trying to remotely connect to it using riak java client(2.1.1) using the following code. client.execute() never returns. I'm attaching the log also.
public class Testing {
public static void main(String[] args) throws ExecutionException,
InterruptedException, UnknownHostException {
RiakClient client = RiakClient.newClient(8098, "192.168.0.102");
// put some stuff
Namespace ns = new Namespace("TestBucket");
Location location = new Location(ns, "TestKey");
String myData = "TestValue";
StoreValue store = new StoreValue.Builder(myData)
.withLocation(location).build();
Response rv = client.execute(store); // << NEVER GETS PAST THIS
System.out.println("write done");
// get some stuff
FetchValue fv = new FetchValue.Builder(location).build();
FetchValue.Response response = client.execute(fv);
String obj = response.getValue(String.class);
System.out.println(obj);
System.out.println("fetch done");
}
}
Log on the console is...

A simple code addition after the following line of your code should fix things for you:
response rv = client.execute(store);
add:
client.shutdown();
to release that connection and continue execution.
Note that you will need to create a new connection for your next request against the database since you closed client or use .executeAsync() in place of .execute().

It appears you are expecting the Riak java client to connect using HTTP API. The Riak java client only connects using protocol buffer; using the HTTP address and port will freeze.

Yoy have to use this, its works fine...
public static void main(String[] args) throws ExecutionException,
InterruptedException, UnknownHostException {
RiakClient client = RiakClient.newClient(8087,"192.168.0.65");
// put some stuff
Namespace ns = new Namespace("TestBucket");
Location location = new Location(ns, "TestKey");
String myData = "TestValue";
StoreValue store = new StoreValue.Builder(myData)
.withLocation(location).build();
client.execute(store); // << NEVER GETS PAST THIS
System.out.println("write done");
// get some stuff
FetchValue fv = new FetchValue.Builder(location).build();
FetchValue.Response response = client.execute(fv);
String obj = response.getValue(String.class);
System.out.println(obj);
System.out.println("fetch done");
}
hope you will also get... !!!

OpenNMS v18 AMQP Message Sending Issue

I cannot get OpenNMS to send messages to an AMQP end point.
I have never had this working and this is the first time i have used OpenNMS and AMQP so it could be down my inexperience.
I have configured RabbitMQ 3.5.7 and tested it as per this question .
It works fine when using an external QPID 0.32 client and also works fine when using either python or perl.
Definition of works fine is that communications are established and the message payload is transmitted into an exchange and then delivered into a backend queue.
Message can then be viewed within the RabbitMQ Admin GUI.
In OpenNMS i have been following the instructs here
Started with the EventForwarder and then tried the AlarmNorthbounder both yield a NullPointerException.
I set up Karaf as follows setting the properties using these statements:-
opennms> config:edit org.opennms.features.amqp.alarmnorthbounder
opennms> propset connectionUrl amqp://simon:simon#/test?brokerlist=\'localhost:5672\'
opennms> propset destination "amqp:onms3/Simon;{'create':'always','node':{'type':'topic'} }"
opennms> propset processorName default-alarm-northbounder-processor
opennms> config:update
opennms> config:list '(service.pid=org.opennms.features.amqp.alarmnorthbounder)'

My assumption was that this was a connectivity issue to the AMQP server of some description. Having faced a number of issues whilst troubleshooting this if i faced the issue from the external jar it was clear from the logs what the issue was.
Is this an issue with OpenNMS?
Does anyone have this working successfully?
Any ideas?
Cheers
Simon

Following guidance from the OpenNMS list I decided to install the QPID Broker v6.0.3 in place of RabbitMQ and messages are flowing no problems now.

Cassandra Java Driver Cold to Hot in 500ms?

I experience a cold to hot (first use) of cluster and session to a local data source (Cassandra) to take 640ms. Any additional connect takes 80 to 100ms so the overhead of the first connect is about 500+ms. Is that normal and is there anything I can do to get this figure down somehow? I use a T410 (i5 2.5GHz).

As one can see the first connection attempt uses up to 600ms and more depending how one might read the figures.

My guess is this has to do with connection initialization. In all currently released versions of the java driver connections are initialized 1 after another synchronously. Fortunately, individual host pools are initialized in parallel, but the connections are not. If you are using 2.0.9, which has a default # of core connections of 8 that could explain why you are seeing slow initialization times. Also if you are using password authentication, that will slow things down quite a bit as well (from ~0-10ms per connection to ~60-120ms).
In java driver 2.0.10, which will be released soon, all connections are initialized in parallel which greatly improves Session initialization. For information see JAVA-701.
