Burrow reporting client_id and owner empty

[christofluethi]

We are currently using

• Burrow: 1.5.0
• Kafka: 2.8.1
• kafka-version in burrow.toml: 2.8.1

We currently do not get client_id and owner from the rest api. Both values are empty.

curl http://localhost:8000/v3/kafka/CLUSTER/consumer/CONSUMERGROUP/lag | jq '.status.partitions[] | {partition: .partition, status: .status, owner: .owner, client_id: .client_id}'

{
  "partition": 0,
  "status": "OK",
  "owner": "",
  "client_id": ""
}
{
  "partition": 1,
  "status": "OK",
  "owner": "",
  "client_id": ""
}
{
  "partition": 2,
  "status": "OK",
  "owner": "",
  "client_id": ""
}
{
  "partition": 3,
  "status": "OK",
  "owner": "",
  "client_id": ""
}
{
  "partition": 4,
  "status": "OK",
  "owner": "",
  "client_id": ""
}
{
  "partition": 5,
  "status": "OK",
  "owner": "",
  "client_id": ""
}
{
  "partition": 6,
  "status": "OK",
  "owner": "",
  "client_id": ""
}
{
  "partition": 7,
  "status": "OK",
  "owner": "",
  "client_id": ""
}

With another installation with the following specs this seems to be working fine:

• Burrow: 1.3.4
• Kafka: 2.8.1
• kafka-version in burrow.toml: 2.2.0

Is there anything we need to change to get the client_id and owner reported correctly?
