[GitHub] kafka pull request #2254: KAFKA-4537: StreamPartitionAssignor incorrectly ad...

    KAFKA-4537: StreamPartitionAssignor incorrectly adds standby partitions to the partitionsByHostState map

    If a KafkaStreams app is using Standby Tasks then `StreamPartitionAssignor` will add the standby partitions to the partitionsByHostState map for each host. This is incorrect as the partitionHostState map is used to resolve which host is hosting a particular store for a key. 
    The result is that doing metadata lookups for interactive queries can return an incorrect host
