We are running 0.8.1.1, am experiencing following issue, any clue
I have 7 topics in my Kafka cluster of 5 nodes. I pushed  1 million messages to 
each topic using perf producer tool (no compression, no acknowledgement) . I 
saw old messages about a bug in 0.8 Consumer code and it is fixed but I am 
still experiencing this issue
/opt/kafka/kafka-0.8.1.1-src/bin/kafka-producer-perf-test.sh --topics 
${dc}-perf-topic${topic} --messages 142857 --message-size 2000 --broker-list 
${listBroker} --threads ${threads} --request-num-acks ${acks} 
--compression-codec ${codec} > ${logFileProd}.${dc}.topic${topic}.log 2>&1

After Producers populated topics, I run 7 consumers to consume from each above 
topic (1 consumer from 1 topic only) using Consumer Perf tool using below 
command
/opt/kafka/kafka-0.8.1.1-src/bin/kafka-consumer-perf-test.sh --zookeeper 
${listZoo}/kafka --from-latest --topic ${dc}-perf-topic${topic} 
--compression-codec ${codec} > ${logFileConsume}.${dc}.topic${topic}.log 2>&1

All my consumers end up with following message 
 start.time, end.time, fetch.size, data.consumed.in.MB, MB.sec, 
data.consumed.in.nMsg, nMsg.secSLF4J: Failed to load class
