I am getting below eror while connecting to Kafka from logstash 5.2.1 and kaka input plugin 5.6.1

> B log4j:WARN No appenders could be found for logger  
> `Preformatted text` (org.apache.kafka.clients.consumer.ConsumerConfig).  
> log4j:WARN Please initialize the log4j system properly.  
> log4j:WARN See [Apache log4j 1.2 - Frequently Asked Technical Questions](http://logging.apache.org/log4j/1.2/faq.html#noconfig) for more info.lockquote

below is my input kafka config:

> kafka{  
> group\_id =\> "topic1"  
> jaas\_path =\> "/"  
> sasl\_kerberos\_service\_name =\> "kafka"  
> kerberos\_config =\> "/etc/krb5.conf"  
> auto\_offset\_reset =\> "latest"  
> topics =\> ["cp1"]  
> #codec =\> "json"  
> bootstrap\_servers =\> ""  
> #type =\> "ocs\_cdr\_data"  
> }  
> }
