--------------------------------------
Summary: 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: Spark Core
Affects Versions: 2.0.0
Reporter: Daniel Nuriyev
Priority: Critical
Fix For: 2.0.3
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>
I 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.
