Re: [VOTE] 0.10.2.1 RC2

2017-04-19 Thread Swen Moczarski
Hi Gwen,
thanks for the new release candidate. Did a quick test, used the RC2 in my
recent project on client side, integration test against server version
0.10.1.1 worked well.

+1 (non-binding)

Swen

[jira] [Created] (KAFKA-4761) NullPointerException if batch.size=0 for producer config

2017-02-13 Thread Swen Moczarski (JIRA)
Swen Moczarski created KAFKA-4761:
-

 Summary: NullPointerException if batch.size=0 for producer config
 Key: KAFKA-4761
 URL: https://issues.apache.org/jira/browse/KAFKA-4761
 Project: Kafka
  Issue Type: Bug
  Components: clients
Affects Versions: 0.10.2.0
 Environment: jdk1.8.0_40
Reporter: Swen Moczarski
Priority: Minor
 Attachments: KafkaProducerTest.java

When setting {{batch.size}} to {{0}} for producer I get the following exception 
when sending a record:

{noformat}
java.lang.NullPointerException
at org.apache.kafka.common.utils.Utils.notNull(Utils.java:315)
at 
org.apache.kafka.clients.producer.internals.RecordAccumulator.append(RecordAccumulator.java:197)
at 
org.apache.kafka.clients.producer.KafkaProducer.doSend(KafkaProducer.java:478)
at 
org.apache.kafka.clients.producer.KafkaProducer.send(KafkaProducer.java:440)
at 
org.apache.kafka.clients.producer.KafkaProducer.send(KafkaProducer.java:360)
at KafkaProducerTest.exposeNpeOnBatchSizeZero(KafkaProducerTest.java:21)
{noformat}

But documentation says:
{quote}
 ... (a batch size of zero will disable batching entirely).
{quote}

Please, see attached test.
