Troubleshooting the DataStax Apache Kafka Connector

Find answers to common issues and errors.

DataStax Apache Kafka Connector writes error message to the Kafka Connect Worker log. The default logger is log4j, which is configured in the file distributed with Apache Kafka and Confluent. If a file is not designated, the logger writes to stdout.
Tip: When the Kafka connect worker first starts, many informational messages are written to the log; most messages are related to system configuration. These messages are harmless and contain startup and configuration information.
