>                 URL: https://issues.apache.org/jira/browse/KAFKA-6648
>             Project: Kafka
>          Issue Type: Bug
>          Components: clients
>    Affects Versions: 1.0.0, 0.11.0.2
>            Reporter: radai rosenblatt

> if (!shouldRetry) {
>    HashMap<String, List<PartitionInfo>> topicsPartitionInfos = new HashMap<>();
>    for (String topic : cluster.topics())
>       topicsPartitionInfos.put(topic, cluster.availablePartitionsForTopic(topic));
>    return topicsPartitionInfos;
> }
> {code}
> this leads to inconsistent behavior upstream, for example in KafkaConsumer.partitionsFor(), where if there's valid metadata all partitions would be returned, whereas if MD doesnt exist (or has expired) a subset of partitions (only the healthy ones) would be returned.
