             Summary: Kafka stream interactive query not returning data when state is backed by rocksdb
                 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


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.
