["Ashwanth Fernando (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-224?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13634451#comment-13634451 ] 

Ashwanth Fernando commented on KAFKA-224:
-----------------------------------------

If you remove the serializer.class, the DefaultEncoder - kafka.serializer.DefaultEncoder is used. This is described in http://kafka.apache.org/quickstart.html. Is this an issue?

>   val props = new Properties();
>   props.put("zk.connect", "127.0.0.1:2181");
>   props.put("producer.type", "async");
>   props.put("batch.size", "50")
>   props.put("serializer.class", "kafka.serializer.StringEncoder");
>   props.put("compression.codec", "1") //gzip
>   val config = new ProducerConfig(props);
> If remove the serializer.class config : props.put("serializer.class", "kafka.serializer.StringEncoder"); The consumer-shell can no longer get the messages published by producer, so it's like there's something wrong, but no exception got.
