In my app I have fabric and DefaultExceptionHandler both set. Order for the same is First Fabric is initialised and started then DefaultExceptionHandler is set.
When any uncaught exception is thrown same is caught in Default Exception and app is restarted after 100 ms. At that point getting the below exception from fabric when activity resumed.

I am trying to compose a worker verticle that will bridge Google cloud PubSub topic subscription with an event-bus of the vert.x by adopting kotlin example of PubSub combined with this answer regarding worker with an infinite blocking loop processing.
It does works but Vert.X keep nagging into the log that Thread blocked by throwing an exception sometime after the message was from PubSub was received (please ignore blocking initialization for now):

I am clearly missing something. Also if you have a better approach that can integrate/unify Google’s PubSub library (that has its own async loop) with Vert.X I’d be happy to hear over my primitive example approach.
The problem is with your while loop.
"Blocking" in this case does not mean that you can just keep running forever.
Your call to it.complete() is never reached, and at some point Vert.x will complain about that.
See the manual on Running blocking code, specifically the WARNING section.
To solve your problem, you will need to schedule your calls to messages.take() in one way or another, for example using setPeriodic. Inside the interval handler, empty your queue with executeBlocking, then give back control by calling complete(), either before or after you have scheduled the processing of the messages, depending if you care about the result.
I am having a problem joining and debugging joining to Akka.NET cluster. I am using version 1.3.8. My setup is following:
Lighthouse
Almost default code from github. Runs in console akka.hocon is following:
lighthouse {
actorsystem: "sng"
}
petabridge.cmd{
host = "0.0.0.0"
port = 9110
}
akka {
loglevel = DEBUG
loggers = ["Akka.Logger.Serilog.SerilogLogger, Akka.Logger.Serilog"]
actor {
provider = "Akka.Cluster.ClusterActorRefProvider, Akka.Cluster"
debug {
receive = on
autoreceive = on
lifecycle = on
event-stream = on
unhandled = on
}
}
remote {
log-sent-messages = on
log-received-messages = on
log-remote-lifecycle-events = on
enabled-transports = ["akka.remote.dot-netty.tcp"]
dot-netty.tcp {
transport-class = "Akka.Remote.Transport.DotNetty.TcpTransport, Akka.Remote"
applied-adapters = []
transport-protocol = tcp
hostname = "0.0.0.0"
port = 4053
}
log-remote-lifecycle-events = DEBUG
}
cluster {
auto-down-unreachable-after = 5s
seed-nodes = []
roles = [lighthouse]
}
}
Working node
Also console (net461) application with as simple as possible startup and joining. It works as excpected. akka.hocon:
akka {
loglevel = DEBUG
loggers = ["Akka.Logger.Serilog.SerilogLogger, Akka.Logger.Serilog"]
actor {
provider = "Akka.Cluster.ClusterActorRefProvider, Akka.Cluster"
}
remote {
log-sent-messages = on
log-received-messages = on
log-remote-lifecycle-events = on
dot-netty.tcp {
transport-class = "Akka.Remote.Transport.DotNetty.TcpTransport, Akka.Remote"
applied-adapters = []
transport-protocol = tcp
hostname = "0.0.0.0"
port = 0
}
}
cluster {
auto-down-unreachable-after = 5s
seed-nodes = ["akka.tcp://sng#127.0.0.1:4053"]
roles = [monitor]
}
}
Not working node
An .NET 4.6.1 library, registerd as COM and started in other (Media Monkey) application with VBA code:
Sub OnStartup
Set o = CreateObject("MediaMonkey.Akka.Agent.MediaMonkeyAkkaProxy")
o.Init(SDB)
End Sub
Akka system is, as in console aplikation, created with standard ActorSystem.Create("sng", config);
akka.hocon:
akka {
loglevel = DEBUG
loggers = ["Akka.Logger.Serilog.SerilogLogger, Akka.Logger.Serilog"]
actor {
provider = "Akka.Cluster.ClusterActorRefProvider, Akka.Cluster"
}
remote {
log-sent-messages = on
log-received-messages = on
log-remote-lifecycle-events = on
dot-netty.tcp {
transport-class = "Akka.Remote.Transport.DotNetty.TcpTransport, Akka.Remote"
applied-adapters = []
transport-protocol = tcp
hostname = "0.0.0.0"
port = 0
}
}
cluster {
auto-down-unreachable-after = 5s
seed-nodes = ["akka.tcp://sng#127.0.0.1:4053"]
roles = [mediamonkey]
}
}

Do you have any idea how to debug and/or resolve this?
As I can see that the first thing I notice in the non-working node the hocon configuration contains different "seed-nodes" address from the working node.
IMHO the "seed-nodes" in all the applications [nodes as called in cluster] withinvthe cluster needs to be same. So in the non-working node instead of
seed-nodes = ["akka.tcp://songoulash#127.0.0.1:4053"]
replace with the below which is in the working node
seed-nodes = ["akka.tcp://sng#127.0.0.1:4053"]
Also, please check the github link for sample https://github.com/AJEETX/Akka.Cluster
and another link https://github.com/AJEETX/AkkaNet.Cluster.RoundRobinGroup
#Rok, Kindly let me know if this was helpful or I can further try to investigate.
One cassandra cluster doesn't have SSL enabled and another cassandra cluster has SSL enabled. How to interact with both the cassandra cluster from a single spark job. I have to copy the table from one server(without SSL) and put into another server(with SSL).
Spark job:-
object TwoClusterExample extends App {
val conf = new SparkConf(true).setAppName("SparkCassandraTwoClusterExample")
println("Starting the SparkCassandraLocalJob....")
val sc = new SparkContext(conf)
val connectorToClusterOne = CassandraConnector(sc.getConf.set("spark.cassandra.connection.host", "localhost"))
val connectorToClusterTwo = CassandraConnector(sc.getConf.set("spark.cassandra.connection.host", "remote"))
val rddFromClusterOne = {
implicit val c = connectorToClusterOne
sc.cassandraTable("test","one")
}
{
implicit val c = connectorToClusterTwo
rddFromClusterOne.saveToCassandra("test","one")
}
}
Cassandra conf:-
spark.master spark://ip:6066
spark.executor.memory 1g
spark.cassandra.connection.host remote
spark.cassandra.auth.username iccassandra
spark.cassandra.auth.password pwd1
spark.serializer org.apache.spark.serializer.KryoSerializer
spark.eventLog.enabled true
spark.eventLog.dir /Users/test/logs/spark
spark.cassandra.connection.ssl.enabled true
spark.cassandra.connection.ssl.trustStore.password pwd2
spark.cassandra.connection.ssl.trustStore.path truststore.jks
Submitting the job:-
spark-submit --deploy-mode cluster --master spark://ip:6066 --properties-file cassandra-count.conf --class TwoClusterExample target/scala-2.10/cassandra-table-assembly-1.0.jar

I am writing a simple piece of Java code, to check my external IP and update my DNS entries if it has changed.
I use NetBeans and HTMLunit. The first part of the code works OK.
My code gets the proper External IP address from WhatIsMyIp.com
The second part, which involves logging into my DNS provider webpage (fastname.no) is attached below.
>
> public void LoginToDNS(HtmlPage LogInPage) throws Exception {
> try (final WebClient webClient = new WebClient()) {
>
> //get the webpage data we're looking for
> // also get the buttons and textfields
> final List<?> forms = LogInPage.getForms();
> final HtmlForm form = LogInPage.getFormByName("form1");
> final HtmlTextInput UsernameField = form.getInputByName("username");
> final HtmlPasswordInput PasswordField = form.getInputByName("password");
> final HtmlButton submit_button = form.getButtonByName("submit");
>
> // Set the Username and pasword
> UsernameField.setValueAttribute("myusername");
> PasswordField.setValueAttribute("mypassword");
>
> // submit the form by clicking the button and get back the control panel page
> final HtmlPage DNSPage = submit_button.click();
> CheckDNSEntries(DNSPage);
>
> }
> }
Although I can see that I have logged in properly (I know, because the page title changes to the correct one), I see an SSL error and the resulting webpage is not what I want.

I am not quite sure whether this is a HTMLunit problem handling JavaScript or it's just my code. Is there a better solution that I can use instead of HTMLunit that will get me where I want to go faster? After all I think the task I want to accomplish is relatively simple.
Try to enable SSL by adding:
webClient.getOptions().setUseInsecureSSL(true);
You can find more documentation here.
EDIT:
In order to hide the HtmlUnit logs, you have to add this:
LogFactory.getFactory().setAttribute("org.apache.commons.logging.Log", "org.apache.commons.logging.impl.NoOpLog");
java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(Level.OFF);
java.util.logging.Logger.getLogger("org.apache.commons.httpclient").setLevel(Level.OFF);
