Kerberos. property 'java.security.auth.login.config'

[jrewerski]

Hi!

In my company we have kerberos and we use keytabs to authenticate. My properties are:
security.protocol: SASL_PLAINTEXT
sasl.mechanism: GSSAPI
sasl.kerberos.service.name: kafka
sasl.jass.config: com.sum.security.auth.module.Krb5LoginModule required useKeyTab=True keyTab="/etc/xxx" principal="kafka/xxx" ;
And I got this problem :

Caused by: java.lang.IllegalArgumentException: Could not find a 'KafkaClient' entry in the JAAS configuration. System property 'java.security.auth.login.config' is not set

how can I set it?

I added keytab and jass.conf in pod

thanks!
