I'm trying to create a site to site connection between 2 Nifi servers.
Nifi1 (Hostname wef2 - running on windows) need to deliver traffic to nifi2 (IP 10.168.233.168 - running on linux) - I defined the connection and all is green but on Nifi1 I'm getting the following error messages
*port ID 0176100c-8d25-196b-1f72-6befa5cab12a is the input port in NIFI2

I am new to Kafka and trying to install and run console consumer but getting error java.lang.IllegalStateException: There are no in-flight requests for node -1
Environment I tried on is as below
Kafka Version kafka_2.13-2.6.0
MacOS java11 Fails
MacOS java 1.8 Fails
Windows 10 Java11 Success
Below are the steps in details which I am performing. The same steps works on Windows.
STEP 1 Download KAFKA
I just downloaded the Kafka from https://www.apache.org/dyn/closer.cgi?path=/kafka/2.6.0/kafka_2.13-2.6.0.tgz
STEP 2 Start zookeeper service, which works fine.
I am starting zookeeper with below command
bin % zookeeper-server-start.sh ../config/zookeeper.properties
here is the zookeeper log

STEP 3 start Kafka - the logs look fine to me.
After that I am starting Kafka using below command
bin % kafka-server-start.sh ../config/server.properties
Kafka startup looks fine with below log tail

STEP 4 Create topic, topic created successfully.
after which I. am creating topic
bin % kafka-topics.sh \

--topic my-topic
Created topic my-topic.
list topic
bin % kafka-topics.sh \
--list \
--zookeeper localhost:2181
my-topic
word-count-input
word-count-output
STEP 5 Run console producer, fails with below error.
but when I try to start the console producer using below command, I am getting exception java.lang.IllegalStateException: There are no in-flight requests for node -1 The same step when I run on windows it works fine, I am getting issue only on Mac.
bin % kafka-console-producer.sh \

Finally I found the issue, the port was being used by sonarqube running on my local but surprisingly when I started kafka there was no error reported.
Honestly, I don't know how Firewall/Antivirus played some role but somehow its linked to this problem.
In my case, Consumer was able to consume messages only once but it throws exception BufferUnderflowException when I started the consumer again.
Turning-Off Firewall/Antivirus was't option for me so I added/enabled advertised.listeners=PLAINTEXT://localhost:9092 configuration in server.properties of kafka-server and afterwards it works as expected.
kafka version: 2.6.0
My norton antivirus firewall settings was causing this issue. I disabled firewall settings and everything started working fine.
I got the same issue. It was happening because sonarqube uses a second port 9092. To avoid this, I suggest to use the sonarqube docker image instead of downloading locally.

I am trying to storm a storm topology but the storm worker refuses to start when I try to run the java command which invokes the worker process I get the following error:
Exception: java.lang.StackOverflowError thrown from the UncaughtExceptionHandler in thread "main"
I am not able to find what problem is causing this. Has anyone faced similar issue
Edit:
when I runt the worker process with flag -V I get the following error:

797 [main] ERROR org.apache.zookeeper.server.NIOServerCnxn - Thread Thread[main,5,main] died
PS: When I run the same topology in local cluster it works fine, only when i deploy in cluster mode it doesnt start.
Just found out the issue. The jar I creted to upload in the storm cluster, was kept in the storm base directory pics. This somehow was creating conflict which was not shown in the log file and actually log file never got created.
Make sure no external jars are present in the base storm folder from where one start storm. Really tricky error no idea why this happens until you just get around it.
Hope the storm guys add this into the logs so that user facing such issue can pinpoint why exactly this is happening.
While running a topology in storm we are getting error like this,
