Daniel Nuriyev commented on SPARK-20036:
----------------------------------------
I placed the explicit dependencies in my pom because the internal dependency of
streaming is on kafka 0.10.0.0.
I have been able to overcome the originally reported issue only when I
explicitly specified 0.10.2.0 in my pom.
> impossible to read a whole kafka topic using kafka 0.10 and spark 2.0.0

> Key: SPARK-20036
> URL: https://issues.apache.org/jira/browse/SPARK-20036
> Project: Spark
> Issue Type: Bug
> Components: Input/Output
> Affects Versions: 2.0.0
> Reporter: Daniel Nuriyev
> Attachments: Main.java, pom.xml

> 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.
