Alex Glikson created KAFKA-4095:
-----------------------------------
Summary: When a topic is deleted and then created with the same
name, 'committed' offsets are not reset
Key: KAFKA-4095
URL: https://issues.apache.org/jira/browse/KAFKA-4095
Project: Kafka
Issue Type: Bug
Components: consumer
Affects Versions: 0.10.0.0, 0.9.0.1
Reporter: Alex Glikson
I encountered a very strange behavior of Kafka, which seems to be a bug.
After deleting a topic and re-creating it with the same name, I produced
certain amount of new messages, and then opened a consumer with the same ID
that I used before re-creating the topic (with auto.commit=false,
auto.offset.reset=earliest). 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.
