> Key: KAFKA-7640
> URL: https://issues.apache.org/jira/browse/KAFKA-7640
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 2.0.0
> Reporter: hitesh gollahalli bachanna
> Priority: Major
> Attachments: intital_data_host.jpeg, rest_api_call_host.jpeg,

>
> I have a kafka stream app running with 36 different instance (one for each
> partition). Each instance come up one after the other. And I am building rest
> service on top of the state to access the data.
> Here some code that I use:
> {code:java}
> StreamsMetadata metadata = streams.metadataForKey(store, key, serializer);
> --> call this find ouy which host has the key
> if (localSelf.host().equals(hostStoreInfo.getHost())) {
> get the key from local store
> }
> else {
> call the remote host using restTemplate
> }{code}
> The problem now is `metadata` object returned has a different host/ip but the
> data is on a different node. I was able to see using some application logs I
> printed. This happens every time I start my application.
> The `allMetadata` method in `KafkaStreams` class says the value will be
> update as when the partition get reassigned. But its not happening in this
> case.
