How could we run the Kafka example in the official Spark project?


How could we run the Kafka example in the official Spark project?



I try to run the simple Kafka example in Spark project.



The spark built properly, so I can run most of the examples, except this Kafka example.



When I run the following command:


bin/run-example streaming.JavaDirectKafkaWordCount localhost:9092 test



I got the following error:


Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/spark/streaming/kafka010/LocationStrategies



Any idea how could we run the Kafka Example properly?



(Kafka client running on port 9092. Using the latest Spark and Kafka, and Java 8)


9092





same problem, if you find a solution...

In my project, finally I connected together Kafka and Spark properly. I realised, using the local mode in Spark script is quite useful during development. Much easier to debug and practice.


local



You can find a detailed, dockerized implementation here: https://github.com/zoltan-nz/kafka-spark-project

api-platform.com Unable to generate an IRI for the item of type

api-platform.com Unable to generate an IRI for the item of type I'm trying to setup my first api-platform instance and have run into some presumably noob questions around IDE. What i'm trying to do is setting up an register and reset entity in order to deal with registrations and password reminders from an app. And then have the entity's passed to a custom controller to do some checks, balances and mails afterwards (haven’t gotten around to that yet). But I keep running into this error when posting to my custom entities: { "@context": "/api/contexts/Error", "@type": "hydra:Error", "hydra:title": "An error occurred", "hydra:description": "Unable to generate an IRI for the item of type "AppXXXUserBundleEntityRegister"", "trace": [ { "namespace": "", "short_class": "", "c

PHP contact form sending but not receiving emails

PHP contact form sending but not receiving emails I have created a contact form using PHP to send the data. The form seems to send fine as there are no errors and success message appears, however I am not receving the emails into the designated inbox. I am using PHPMailer as I originally tried just using the php 'mail' command which I now understand is a bit hit and miss. I cannot see why I would not be receving the emails so I would be very grateful for any help that could be given. I'm quite new to PHP so please be patient with me :) <?php use PHPMailerPHPMailerPHPMailer; use PHPMailerPHPMailerException; $msg = ""; if (isset($_POST['submit'])) { require 'phpmailer/src/Exception.php'; require 'phpmailer/src/PHPMailer.php'; require 'phpmailer/src/SMTP.php'; function sendemail ($to, $from, $body) { $mail = new PHPMailer(true); $mail->setFrom($from); $mail->addAddress($to); $ma

Do graphics cards have individual ID by which single devices can be distinguished?

Do graphics cards have individual ID by which single devices can be distinguished? I have several graphics cards of the same manufacturer and same model and I want to distinguish them not only by the pcie socket they reside in but by some individual value I can read from the hardware. Is there such value and if so what would it be called and how could I access it? Right now I'm using modern nvidia cards (10xx series) and nvidia inspector.but I'd prefer if there was any value that was also applicable to amd. I have programming and scripting knowledge. I am running Windows 10 1 Answer 1 This is a powershell example to pull information from video cards. The DeviceID is supposed to be unique but only if the manufacturer supports Windows Display Driver Model (WDDM). (I copied this directly from docs.microsoft.com) $strComputer = "." $colItems = get-wmiobject -class "Win32_VideoC
