SOFT COMPANY - NEJJAR, Azeddine commented on KAFKA-3102:
--------------------------------------------------------
Hello,
Have you find any solution for Kafka connection error.
I would like to configure Kafka to connect on sasl zookeeper.
There in my error message :
Using builtin default etypes for default_tkt_enctypes
default etypes for default_tkt_enctypes: 17 16 23 1 3.
[Krb5LoginModule] authentication failed
Checksum failed
[2016-09-26 16:30:13,159] WARN SASL configuration failed:
javax.security.auth.login.LoginException: Checksum failed Will continue
connection to Zookeeper server without SASL authentication, if Zookeeper server
allows it. (org.apache.zookeeper.ClientCnxn)
Thanks a lot for your help,
Sincerely,
Azeddine
