Expected one of [A-Za-z0-9_-], [\t\n \n], "#","=>" ... after input {

The error comes in line 19 column 19 in after input{}
I think the configuration is correct but the error shows there's unexpected character

   jdbc_driver_library => "$DRIVER_PATH"

You are missing a } to close the input section, so logstash is trying to parse filter as if it were an input.

Test your .conf file with the optimal parameter: -t or --config.test_and_exit before you run it. Check more options.
