Mohit Anchlia updated KAFKA-3102:
---------------------------------
Description:
Server disconnects from the zookeeper with the following log, and logs are not
indicative of any problem. It works without the security setup however.
I followed the security configuration steps from this site:
http://docs.confluent.io/2.0.0/kafka/sasl.html
In here find the list of principals, logs and Jaas file:
1) Jaas file
KafkaServer {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
storeKey=true
keyTab="/mnt/kafka/kafka/kafka.keytab"
principal="kafka/[email protected]";
};
Client {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
storeKey=true
keyTab="/mnt/kafka/kafka/kafka.keytab"
principal="kafka/[email protected]";
};
2) Principles from krb admin
