Kafka Connect in debug mode

Question

I am using native apache kafka and not confluent's edition of kafka.

I am using using kafka jdbc connector pluggin. I intend to put a break point and inspect through my IDE (intelliJ).

How to make connect listen on a debug port and suspend. I referred What is a simple, effective way to debug custom Kafka connectors? but that's for confluent kafka

I am looking for below confluent configuration equivalents for apache kafka

CONNECT_DEBUG=y; export DEBUG_SUSPEND_FLAG=y;

Answer 1

confluent's edition of kafka

There is no such thing. Both are the same Apache Kafka, so the scripts are the same (which is kafka-run-class)

What you reference, the confluent CLI command, is intended for local deployments of the Confluent stack, just redirects CONNECT_DEBUG into KAFKA_DEBUG

Therefore, it is always KAFKA_DEBUG for all Kafka Components (including Zookeeper, surprisingly) not CONNECT_DEBUG specifically for Connect.
