Kafka 0.8.2.2 - Compact mode not work - apache-kafka

Question

I am new beginner of kafka, i try to use COMPACT mode in kafka.
I look kafka document, I think setting log.cleaner.enable=true and log.cleanup.policy=compact for COMPACT modem, but it seem not work.
Could you please help me. Thanks.
environment
Ubuntu 14.04.3 LTS
Kafka kafka_2.11-0.8.2.2
kafka config
log.retention.ms=10000
log.retention.check.interval.ms=1000
log.cleaner.enable=true
log.cleaner.delete.retention.ms=1000
log.cleaner.backoff.ms=1000
log.cleaner.min.cleanable.ratio=0.01
log.cleanup.policy=compact
At kafka log, i see 'INFO [kafka-log-cleaner-thread-0], Starting (kafka.log.LogCleaner)’, so i think success to enable COMPACT mode.
I follow QUICK START of kafka document, and input some data to test topic.

I expect only keep on same key, so 22:23:45 and 22:24:05 message will be removed.
Thanks for morganw suggest. I have been push message of has key.
