While connecting to the consumer, you are not giving a zookeeper link. I don't see that in code also(SimpleProducer.java). How does the code or from the command line it identifies the zookeeper?
Hello Sir, Ur teaching is awesome and easy to understand.. Can you please give us a tutorial based on Confluent Kafka.. Please
Agree. It will be very helpful.
Hello Sir, can you please add a video related to twitter feed so that we can have a real time exposure on Kafka.Actually I was trying to use twitter producer API as you have mention in this video but it is was showing error while compiling the code. If possible please share a twitter producer code in your website.
[2018-10-06 19:09:30,583] WARN [Consumer clientId=consumer-1, groupId=console-consumer-75171] Error while fetching metadata with correlation id 2 : {SimpleProducerTopic=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)
hello sir i got this error when i console consumer i am running kafka on my local machine , any idea what i am doing wrong ?
Why not use Maven or Gradle as a build tool? Is there any specific advantage in using SBT?
You can use any dependency management tool or none. All you need to ensure is that the Kafka imports get resolved and you should be good.
showing this error SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". Let me know if i need to add any jar file and how to add ?
slf4j-log4j binding dependency is needed.
Hi Sudharshan,
Please add the following dependency in pom.xml
org.slf4j
slf4j-log4j12

Can we have a sample program for producer and consumer for kafka in C or C++ language.
Hi Manish,
Do we have Kafka lib in c or C++ ? glad to hear if you have found any alternative.Since Kafka is written in Java and Scala, not sure if it is achievable.
please can you tell me ,How to start all services in Kafka.Is it any command for it.
Hey,
What kind of services were you looking for ? Please specify details.
sir after running sbt command in @kafka-1-vm:~/kafka_projects$ sbt . am not able to get promt back. i will be in ''sbt:kafka_projects>'' . there i coudnt run any command. pls help.
Hi Sushma !
When you issue sbt ., it launches sbt server that will have all the information about your project. We run this command for issuing project specific commands.
For example, if name of my project is demo, I will cd to that directory and then issue sbt command.
sbt prompt gets displayed.
You can use following commands compile then run and at the last exit ...
Hope it works.
Can you do the same for python
Hey, how just wanted to not that you shut down the sbt:kafka projects server without really explaining how, im sure by the time you read this ill have found out how, but maybe include it on your website
Okay, so you used the command ctrl c, in case anyone comes looking to the comments for it
My bad, when I was recording it, I had it very clear in my mind that I need an annotation for Ctrl+C. But I missed it later. I will try to add it using RUclips annotation. Thanks for highlighting it.
Nice quick response! Yeah maybe you could add a video early in the list, or on your website quickly describing the different shortcuts you use, like the clear window one etc. I also felt uncomfortable just clicking ctrl O and ctrl X without really understanding what they did (like where in the vm am i going when i exit etc)
