Burrow returning empty topic/consumer lists

[g-lok]

After giving up on using our cluster SASL-Plaintext authentication/encryption (see #380 (comment)), I've tested burrow with simple plaintext (no encryption/authentication) to confirm that it can connect at all. It does seem to connect without error,

but returns empty lists of topics and consumers when queried:

$ curl https://my.burrow:8443/v3/kafka/myclustername/topic
{"error":false,"message":"topic list returned","topics":[],"request":{"url":"/v3/kafka/myclustername/topic","host":"my.burrow"}}

$ curl https://my.burrow:8443/v3/kafka/myclustername/consumer
{"error":false,"message":"consumer list returned","consumers":[],"request":{"url":"/v3/kafka/myclustername/consumer","host":"my.burrow"}}

Kafka ACLs:

Current ACLs for resource `Topic:LITERAL:__consumer_offsets`:
  User:* has Allow permission for operations: All from hosts: *
  User:ANONYMOUS has Allow permission for operations: All from hosts: *

Current ACLs for resource `Group:LITERAL:*`:

Using confluent kafka 2.0.0 (which I believe is kafka v. 0.9.0 or 0.9.0.0). I have tried this with various combinations of the above settings (such as noverify set to true or false), kafka 0.9.0 vs 0.9.0.0, direction connections to zookeeper/kafka vs. AWS ELBs, etc. Nothing seems to work

closing. Turns out that there was no plaintext listen set up on this cluster, despite the fact that burrow 'successfully' started up and connected to it. I may open a separate ticket for that, not sure if that's something that warrants one
