Jason Gustafson updated KAFKA-8442:
-----------------------------------
Description:
If there is no leader for a partition, the Metadata API returns an empty ISR.
When using the `--bootstrap-server` option with `kafka-topics.sh`, this leads
to the following output:
{code}
Topic:foo PartitionCount:1 ReplicationFactor:2
Configs:segment.bytes=1073741824
Topic: foo Partition: 0 Leader: none Replicas: 1,3 Isr:
{code}
When using `--zookeeper`, we display the current ISR correctly:
{code}
Topic:foo PartitionCount:1 ReplicationFactor:2 Configs:
Topic: foo Partition: 0 Leader: -1 Replicas: 1,3 Isr: 1
{code}
To avoid confusion, we should make this output consistent or at least not
misleading. We should either change the Metadata API to print the ISR when we
have it or we can change the output of the topic command to `N/A` or something
like that.
