While the latest offsets seemed up to date, the > *committed* offset (returned by committed() method) was an *old* offset, from > the time before the topic has been deleted and created. > I would have assumed that when a topic is deleted, all the associated > topic-partitions and consumer groups are recycled too. > I am using the Java client version 0.9, with Kafka server 0.10. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
