Re: Kafka server occure java.nio.BufferUnderflowException

[Jun Rao]

This could also be an implementation issue with the wire protocol in the c
library. Could you dump out the bytes in the request and see if it matches
the protocol specified in our wiki (
https://cwiki.apache.org/confluence/display/KAFKA/A+Guide+To+The+Kafka+Protocol
)?

Thanks,

Jun
