huxi commented on KAFKA-4373: ----------------------------- Could you paste your client code and the stack trace? > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
