---------------------------------
Summary: ConsoleProducer compresses messages and ignores the
--compress flag
Key: KAFKA-634
URL: https://issues.apache.org/jira/browse/KAFKA-634
Project: Kafka
Issue Type: Bug
Components: core
Affects Versions: 0.7
Reporter: Paul Garner
I am using the kafka-producer-shell.sh script without the --compress option
however my messages seem to be gzipped
the docs say compression is off by default:
http://incubator.apache.org/kafka/configuration.html
The only producer.properties file I can find is at:
/home/ubuntu/kafka-0.7.2-incubating-src/config/producer.properties
In there is:
compression.codec=0
My process looks like:
root 1748 1746 0 Nov19 ? 00:02:37 java -Xmx512M -server
-Dlog4j.configuration=file:/usr/local/bin/kafka/../config/log4j.properties
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.authenticate=false

kafka.producer.ConsoleProducer --topic logtail --zookeeper x.x.x.x:2181
But the messages come out gobbledegook unless I use a client that understands
compressed messages, and in that client it identifies the bit as set to 1, gzip
compression.

This seems to be a bug in ConsoleProducer. It also compresses messages and
ignores the --compress flag. Could you file a jira?
Thanks,
Jun
