Reporting Issues

If you believe you encountered a bug, please file a GitHub issue, and check if your problem has already been reported. Given the high volume of issues and questions we see, we may not be able to examine your issue in detail without a corresponding unit test to reproduce behavior.

For any trouble with your Druid setup, here's a list of a few things to include in your message that will help us with debugging:

1) Druid version and setup information

2) Relevant logs on any Druid nodes, especially exceptions

3) Configuration settings, including runtime.properties, system properties and JVM flags
