Daniel Nuriyev updated SPARK-20036:
-----------------------------------
Description:
I use kafka 0.10.1 and java code with the following dependencies:
<dependency>
<groupId>org.apache.kafka</groupId>
<artifactId>kafka_2.11</artifactId>
<version>0.10.1.1</version>
</dependency>
<dependency>
<groupId>org.apache.kafka</groupId>
<artifactId>kafka-clients</artifactId>
<version>0.10.1.1</version>
</dependency>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-streaming_2.11</artifactId>
<version>2.0.0</version>
</dependency>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-streaming-kafka-0-10_2.11</artifactId>
<version>2.0.0</version>
</dependency>
The code tries to read the whole topic using:
kafkaParams.put("auto.offset.reset", "earliest");
Using 5 second batches:
jssc = new JavaStreamingContext(conf, Durations.seconds(5));
Each batch returns empty.
I debugged the code I noticed that KafkaUtils.fixKafkaParams is called that
overrides "earliest" with "none".
Whether this is related or not, when I used kafka 0.8 on the client with kafka
0.10.1 on the server, I could read the whole topic.

I use this as a base:
https://spark.apache.org/docs/latest/streaming-kafka-0-10-integration.html
But I use direct stream:
KafkaUtils.createDirectStream(jssc,LocationStrategies.PreferConsistent(),
ConsumerStrategies.<String, String>Subscribe(
topics, kafkaParams, fromOffsets
)
)
