[jira] [Commented] (DRILL-6111) NullPointerException with Kafka
Storage Plugin
[ https://issues.apache.org/jira/browse/DRILL-6111?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16345479#comment-16345479 ]
Anton Gozhiy commented on DRILL-6111:
-------------------------------------
Reproduced with the Drill version 1.13.0-SNAPSHOT (commit id: a9ea4ec1c5645ddab4b7aef9ac060ff5f109b696)
*Prerequisites:*
*1.* Kafka topic was created with 5 partitions:
{code:java}
bin/kafka-topics.sh --create --zookeeper <zk node> --replication-factor 1 --partitions 5 --topic test
{code}
*2.* Test data - json file with 100000 key-value records:
{code:java}
{"key": "value_1"}
{"key": "value_2"}
....
{"key": "value_100000"}
{code}
*3.* The data is added to the topic:
{code:java}
cat test_kafka_big_file.json | bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test
{code}
*4.* Kafka storage plugin is enabled in Drill with the following configuration:
{code:java}
{
"type": "kafka",
"kafkaConsumerProps": {
"key.deserializer": "org.apache.kafka.common.serialization.ByteArrayDeserializer",
"auto.offset.reset": "earliest",
"bootstrap.servers": "localhost:9092",
"enable.auto.commit": "true",
"group.id": "drill-query-consumer-1",
"value.deserializer": "org.apache.kafka.common.serialization.ByteArrayDeserializer",
"session.timeout.ms": "30000"
},
"enabled": true
}
{code}
*Steps:*
*1*. Run the following query from Drill:
{code:java}
select * from kafka.test limit 5;
{code}
*Expected result:*
Query should be completed successfully.
*Actual result*
NPE happens:
{noformat}
