         Environment: ubuntu 14.04

Hi
I wrote a simple kafka streams application. After I start the stream, if I call KafkaStreams.store immediately, I will get InvalidStateStoreException:

{code:java}
org.apache.kafka.streams.errors.InvalidStateStoreException: the state store, my-table, may have migrated to another instance.
{code}

Here is the complete code :

{code:java}
 final StreamsBuilder builder = new StreamsBuilder();

        final KTable<String, Integer> table = builder.table(TOPIC_NAME , Consumed.with(Serdes.String(), Serdes.Integer(),
                new FailOnInvalidTimestamp(), Topology.AutoOffsetReset.EARLIEST), Materialized.as("my-table"));

        Topology topology = builder.build();
        Properties props = new Properties();
        props.setProperty(StreamsConfig.APPLICATION_ID_CONFIG,"my-streams-app");
        props.setProperty(StreamsConfig.BOOTSTRAP_SERVERS_CONFIG,"localhost:9092");
        props.setProperty(StreamsConfig.COMMIT_INTERVAL_MS_CONFIG,"10000");
        final KafkaStreams streams = new KafkaStreams( topology , props );
        Runtime.getRuntime().addShutdownHook(new Thread(){
            @Override
            public void run() {
                streams.close();
            }
        });
        streams.start();
        ReadOnlyKeyValueStore<String, Integer> store streams.store(table.queryableStoreName(), QueryableStoreTypes.keyValueStore());

{code}
However if after start() method, I write Thread.sleep( SOME_AMOUNT ) I will not get the exception any more.

I wonder if it is a bug or I did something wrong.
