             Summary: Kafka Consumer API jumping offsets
                 Key: KAFKA-4373
                 URL: https://issues.apache.org/jira/browse/KAFKA-4373
             Project: Kafka
          Issue Type: Bug
          Components: consumer
            Reporter: Srinivasan Venkatraman


Hi,

I am using Kafka Version 0.10.0.1 and java consumer API to consume messages from a topic. We are using a single node kafka and zookeeper. It is sometimes observed that the consumer is losing a bulk of message. We are unable to find the exact reason to replicate the issue.
The scenario is:
Consumer polls the topic.
Fetches the messages and gives it to a thread pool to handle the message.
Waits for the threads to return and then commits the offsets.
