Subject Fwd: Re: Kafka SSL Configuration Problems
Date Mon, 01 Feb 2016 18:02:34 GMT
Hello Nazario,

Could you try it by creating a new topic?

Thank you,
Anirudh
That works. At least it is saying that it is registering now with the SSL
side.


[2016-02-01 12:29:40,184] INFO Registered broker 0 at path /brokers/ids/0
with addresses: PLAINTEXT -> EndPoint(servername,9092,PLAINTEXT),SSL ->
EndPoint(servername,9093,SSL) (kafka.utils.ZkUtils)


Thank you.

Now to the next problem. :-) Still related to SSL.


The producer is not giving any more LEADER_NOT_AVAILABLE errors. but is now
having this problem instead.

Consumer is connecting too but not receiving any data
