> `kafka-consumer-groups.sh --describe --all-groups` fails with `org.apache.kafka.common.errors.UnknownTopicOrPartitionException: This server does not host this topic-partition.` if single group has metadata for a topic that was recently deleted. 
> As impact this prevent admin from viewing the group metadata for the whole cluster. 
> Instead we should either 
> - follow the same approach when we calculate the lag which print a place holder `-` when it is not applicable to calculate the metadata. 
> - or we exclude instances with deleted topics 
> Currently I am more leaning into the first option with `-` as placeholder.
