Following is my config file called jdbc.conf:

input {
  jdbc {
    jdbc_driver_library => "/etc/logstash/usr/share/java/mysql-connector-java-8.0.30.jar"
    jdbc_driver_class => "com.mysql.jdbc.Driver"
    jdbc_connection_string => "jdbc:mysql://localhost:3306/logsql"
    jdbc_user => "houssem"
    jdbc_password => "Oypoyp@202"
    statement => "SELECT * from CONFIG_CUSTOMER"
  }
}

output{
  file {
   path => "/etc/logstash/new_data.txt"
  }
}
~                                                                              
~

and i run this command to start the pipeline:

sudo /usr/share/logstash/bin/logstash -f jdbc.conf

Is this path correct?

 jdbc_driver_library => "/etc/logstash/usr/share/java/mysql-connector-java-8.0.30.jar"

Your log error says that it cannont find this file in the specified path.

Error: unable to load mysql-connector-java-8.0.30.jar from :jdbc_driver_library, no such file to load -- mysql-connector-java-8.0.30.jar

Hello @leandrojmp,
yes the path is correct
here it is :

imagen
the following images shows that that path is correct

do you have any idea why he might says no such file to load while the path is correct
