why Data is not going to kafka ? receiving error : "PutKafka Error : failed while waiting for acks from kafka"

New Contributor

Hi All,

I'm trying out the below tutorial:

https://hortonworks.com/tutorial/realtime-event-processing-in-hadoop-with-nifi-kafka-and-storm/secti...

i'm getting "PutKafka Error : failed while waiting for acks from kafka" error though i see some values under "In" & "Read".

but i see attached consumer console error.

Also,i see something strange here. the kafka broker gets stopped by itself after a while, on Ambari.

please help me on this & find supporting attachments. @jmedel @Predrag Minovic @Artem Ervits

Note: I'm using HDP 2.6 sandbox

Regards,

Akshay
