Using an alternate location for the Kerberos files

When using a location other than /etc for the krb5.conf file, add the custom path to Kafka Connect and Kerberos environment variables.

When using a location other than /etc for the krb5.conf file, add the custom path to Kafka Connect and Kerberos environment variables. If the Kerberos configuration file is not available on the system, get it from the Kerberos system administrator.

Tip: See Default paths.

Procedure

Kerberos clients

Configure the path to file for Kerberos clients, such as kinit, klist, and kdestroy.
Set the path to the file in the KRB5_CONFIG environment variable:
```
export KRB5_CONFIG="path_to_file"
```

Kafka Connect framework

Configure the path to the file for the DataStax Apache Kafka Connector.
Add the system property, java.security.krb5.conf, to the KAFKA_OPTS environment variable:
```
export KAFKA_OPTS=$KAFKA_OPTS -Djava.security.krb5.conf="path_to_file"
```
Note: Both connect-standalone and connect-distributed support specifying extra JVM options through the KAFKA_OPTS environment variable.
