gaborgsomogyi opened a new pull request #29729: URL: https://github.com/apache/spark/pull/29729
### What changes were proposed in this pull request? Deprecated `KafkaConsumer.poll(long)` API calls may cause infinite wait in the driver. In this PR I've changed `KafkaConsumer` calls to `AdminClient` calls. Please see the following [doc](https://docs.google.com/document/d/1gAh0pKgZUgyqO2Re3sAy-fdYpe_SxpJ6DkeXE8R1P7E/edit?usp=sharing) for further details. The PR contains the following changes: * Replaced `KafkaConsumer` calls to `AdminClient` calls * GroupId prefix feature removed from driver (`AdminClient` doesn't need any GroupId) * GroupId override feature removed from driver (`AdminClient` doesn't need any GroupId) * Additional unit tests * Code comment changes * Minor bugfixes here and there * Removed Kafka auto topic creation feature (please see doc for rationale). In short, it's super hidden, not sure anybody ever used in production + error prone. ### Why are the changes needed? Driver may hang forever. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Existing + additional unit tests. Cluster test with simple Kafka topic to another topic query. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
