And I create a state store as below
StateStoreSupplier avgStore = Stores.create("avgStore")
.withKeys(Serdes.String())
.withValues(Serdes.String())
.persistent()
.build();
Any idea of how to fix this?
Did you configure multiple threads within your application instance? If yes, it may be due to a known issue in older versions of Kafka, where the underlying consumer used by Kafka Streams (in the app instance) can take too long to rebalance, causing itself to be kicked out of the consumer group (and hence triggering another consumer group rebalance) while it is still under the first rebalance process.
The following error messages in your stacktrace indicate that you are actually running into the problem I described above:
Exception in thread "StreamThread-1" org.apache.kafka.streams.errors.StreamsException: Failed to rebalance at org.apache.kafka.streams.processor.internals.StreamThread.runLoop(StreamThread.java:299) at org.apache.kafka.streams.processor.internals.StreamThread.run(StreamThread.java:218) Caused by: org.apache.kafka.streams.errors.ProcessorStateException: Error while creating the state manager
The problem is summarized in this Apache Kafka ticket:
https://issues.apache.org/jira/browse/KAFKA-3758
A recent change to the underlying Kafka consumer client fixes this issue:
https://cwiki.apache.org/confluence/display/KAFKA/KIP-62%3A+Allow+consumer+to+send+heartbeats+from+a+background+thread
However it is not included in an official Kafka release yet and, as of today, is available only in Apache Kafka trunk
. If you are able to run your app with Kafka trunk
you can verify if this problem has gone away already.
I also saw this problem when the user didn't have permissions to write to the default state.dir
When I changed the following property to a dir w/good permissions everything was fine:
property.put(StreamsConfig.STATE_DIR_CONFIG, "{goodDir}")
This was observed in 0.10.2
