When I start elasticsearch, kafka logs get filled with those exceptions:

kafka.common.OffsetOutOfRangeException: Request for offset 531 but we only have log segments in the range 0 to 23.

Any idea why does it try to read from index 531?

This is how I added my messages to kafka:
kafka-console-producer.sh --topic test --broker-list localhost:9092
test1
msg2
...

This is how I created the kafka river:

curl -XPUT 'localhost:9200/_river/test_river/_meta' -d '{
"type" : "kafka",
"kafka" : {
"broker_host" : "localhost",
"broker_port" : 9092,
"zookeeper" : "localhost",
"message_handler_factory_class" : "org.elasticsearch.river.kafka.JsonMessageHandlerFactory",
"topic" : "test",
"partition" : "0"
}
}'
{"_index":"_river","_type":"test_river","_id":"_meta","_version":1,"created":true}

Hi,
I installed elasticsearch-river-kafka and restart the elasticsearch. when I create a new
river, it cat not started.
There are some error message in the elasticsearch.log:

Hi,

I am using kafka_2.9.2-0.8.1.1 version of kafka and the kafka river plugin.
I get this error, even though all my configurations are correct.
I am not sure why this exception is encountered.

If I have 5 elastic search node in one custer,After I create one kafka river,This river only run in one node, Am I right?

I think ,that is not better than running several consumers to pull data from kafka to es cluster.Does that make sense?

bulkSize = XContentMapValues.nodeIntegerValue(indexSettings.get("bulk_size_bytes"), 10_1024_1024);

So if I input 10485760 as bulk size bytes ,the final bulk size would be 1?

Getting ready to set things up and noticed that replacing the .7.2 jar with the .8 one causes a compile issue. Poking around at the code for SimpleConsumer but not 100% what I'm doing in there yet. Thought I'd ping first to see if anyone had tried to do this yet.

I hava 1 zookeeper and 2 kafka servers
each of kafka has 5 partition,So I need to create 10 rivers.

I just change the "broker_host" ,partition in each of kafka is 0-5,is that right
