Kafka >> mail # user >> kafka.common.FailedToSendMessageException - 0.8

Copy link to this message
Re: kafka.common.FailedToSendMessageException: Failed to send messages after 3 tries.
To debug this I would leave only one broker in the list and look at the
broker log on that machine and the producer machine. Make sure that the
log4j config file is in your class path otherwise it will not initialize
properly. Did you try having the broker on the same machine with the
producer? Does that work?
