-----------------------------------
Summary: Optimize `kafka-consumer-groups.sh` to return the offset
info of other partitions even when the leader of some partitions are missing
Key: KAFKA-19435
URL: https://issues.apache.org/jira/browse/KAFKA-19435
Project: Kafka
Issue Type: Improvement
Components: admin
Affects Versions: 4.0.0
Reporter: kangning.li
Assignee: kangning.li
When we use the `{{{}kafka-consumer-groups.sh`{}}} script to query the LAG of
some consumer group, if the leader of the corresponding topic-partition is
missing, it will directly throw an exception, which may cause the following
problems:
# There are 10 partitions in total, but if only 1 partition lacks a leader,
users will be unable to view the LAG of the other 9 partitions.
# Throwing an exception directly will subconsciously make users think that
there is a major failure in the cluster.
Perhaps we can optimize this script to return as much information as possible
instead of throwing an exception directly.
