I'm trying to write data to Kafka broker authenticated with Kerberos with GSSAPI and SASL. When I start the logstash agent it errors out with Receive Timeout from Kerberos but when i use `kinit` to get the ticket from kerberos, it works perfectly fine without any issues.

Logstash Config:

```auto
     input {
      file {
        path => "<path of log file to monitor>"
      }
    }
    output {
      kafka {
            topic_id => "<topic>"
            bootstrap_servers => "broker-list"
            compression_type => "snappy"
            jaas_path => "<path/to/jaas/config/file>"
            kerberos_config => "/etc/krb5.conf"
            sasl_kerberos_service_name => "kafka"
            security_protocol => "SASL_SSL"
            client_id => "<unique identifier of client>"
            ssl_truststore_location => "<ssl truststore in jks format>"
            ssl_truststore_password => "<password for truststore>"
        }
    }

```

Logstash version: 7.9.2

How do i fix this issue?
