             Summary: StreamsException is thrown after the changing `partitions`
                 Key: KAFKA-6063
                 URL: https://issues.apache.org/jira/browse/KAFKA-6063

            Reporter: Akihito Nakano


"org.apache.kafka.streams.errors.StreamsException" is thrown in following case.

h3. Create topic

```
$ bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 
1 --partitions 6 --topic word-count-input
```

h3. Create Kafka Streams Application

```
public class WordCountApp {
    public static void main(String[] args) {
        Properties config = new Properties();
        config.put(StreamsConfig.APPLICATION_ID_CONFIG, 
"wordcount-application");
...
...
```

h3.  Ensure that it works fine

```
$ java -jar wordcount.jar

KafkaStreams processID: b4a559cb-7075-4ece-a718-5043a432900b
        StreamsThread appId: wordcount-application
...
...
```

h3.  Change "partitions"

```
$ bin/kafka-topics.sh --alter --zookeeper localhost:2181 --partitions 8 --topic 
word-count-input
Adding partitions succeeded!
```

h3.  When I start Application, StreamsException is thrown

```
$ java -jar wordcount.jar

KafkaStreams processID: 8a9cbf03-b841-4cb2-9d44-6456b4520522
        StreamsThread appId: wordcount-applicationn
...
...

Exception in thread 
"wordcount-application-8a9cbf03-b841-4cb2-9d44-6456b4520522-StreamThread-1" 
org.apache.kafka.streams.errors.StreamsException: Could not create internal 
topics.
```

If I change the application id, Application works again.
