> quota_tests.py is failing. Specifically for this test:
> [INFO:2020-05-11 19:22:47,493]: RunnerClient: Loading test \{'directory':
> '/opt/kafka-dev/tests/kafkatest/tests/client', 'file_name': 'quota_test.py',
> 'method_name': 'test_quota', 'cls_name': 'QuotaTest', 'injected_args':
> {'quota_type': 'client-id', 'override_quota': False}}
> I log into the docker container and do
> /opt/kafka-dev/bin/kafka-configs.sh --bootstrap-server ducker03:9093
> --describe --entity-type clients --command-config
> /opt/kafka-dev/bin/hi.properties
> and the command return
> Configs for the default client-id are consumer_byte_rate=2000000.0,
> producer_byte_rate=2500000.0
> Configs for client-id 'overridden_id' are consumer_byte_rate=1.0E9,
> producer_byte_rate=1.0E9
> Seems like the config is properly but the quota is not effective
>
> For investigation, I added a logging at {{AdminZKClient.changeConfigs()}}
> def changeConfigs(entityType: String, entityName: String, configs:
> Properties): Unit = {
> warn(s"entityType = $entityType entityName = $entityName configs =
> $configs")
> ...
> }
> And use --bootstrap-server and --zookeeper to --alter the default client
> quota. I got
> Alter with --zookeeper:WARN entityType = clients entityName = <default>
> configs = \{producer_byte_rate=1000000000, consumer_byte_rate=1000000000}
> (kafka.zk.AdminZkClient)
> and
> Alter with --bootstrap-server:WARN entityType = clients entityName =
> %3Cdefault%3E configs = \{producer_byte_rate=1000000000,
> consumer_byte_rate=1000000000} (kafka.zk.AdminZkClient)
> I guess the encoding difference might cause the issue. The encoding happens in
> Sanitizer.sanitize()
