Kevin created KAFKA-8278:
----------------------------
Summary: MockConsumer.poll and MockConsumer.wakupe are both
synchronized
Key: KAFKA-8278
URL: https://issues.apache.org/jira/browse/KAFKA-8278
Project: Kafka
Issue Type: Bug
Components: unit tests
Affects Versions: 2.0.1
Reporter: Kevin
The MockConsumer's wakeup() and poll() methods are synchronized where the
normal KafkaConsumer's are not. This means that code written using the example
in the "Multi-threaded Processing" of the [KafkaConsumer
docs]([https://kafka.apache.org/20/javadoc/org/apache/kafka/clients/consumer/KafkaConsumer.html])
cannot be tested with the MockConsumer, as a long-running poll will not be
aborted by a call to wakeup() because wakeup() will not execute due to poll()
holding the object lock.
