Todd created KAFKA-6856:
---------------------------
Summary: Consumer Group hung in initialization/bad state
Key: KAFKA-6856
URL: https://issues.apache.org/jira/browse/KAFKA-6856
Project: Kafka
Issue Type: Bug
Reporter: Todd
Fix For: 1.0.0
All attempts to use a consumer group for any topic fail.
When trying to use kafka-consumer-groups.sh on the given consumer group, it
responds with message waiting for group to initialize. We are not sure how to
delete the consumer group, since we have removed all topics associated with the
group as well as ceased all activity to the group, and removed all consumers,
we thought it should have automatically been removed.
Not sure what logs to look at to get additional information.
Example of commands. 1st is failure example, 2nd is good example:
# ./kafka-consumer-groups.sh --bootstrap-server hs22n56.gpfs.net:9092
--describe --group 158_6372129557625143312_audit --command-config
group.properties
Note: This will not show information about old Zookeeper-based consumers.
*Error: Executing consumer group command failed due to The consumer group
command timed out while waiting for group to initialize:*
#
# ./kafka-consumer-groups.sh --bootstrap-server hs22n56.gpfs.net:9092
--describe --group 151_6372129557625143312_audit --command-config
group.properties
Note: This will not show information about old Zookeeper-based consumers.
