Subject Re: remote kafka producer -- kafka.common.FailedToSendMessageException: Failed to send messages after 3 tries
Date Tue, 18 Aug 2015 02:17:02 GMT
Hi, All:

      Finally I fixed this bug.

1. set advertised.host.name at config/server.properites as AWS
*private IP* address
(not public *DNS*)
2. comment host.name at config/server.properites
3. In remote java producer:
props.put("metadata.broker.list",  borkerPrivateIp+ ":9092");
The value brokerPrivateIp is same as advertised.host.name
 at config/server.properites

     This bug blocked me a while...

Sincerely,
Selina
