Invalid JDBC URL:

Error message

Invalid JDBC URL: 

What it means

parseDriverUrl strips the jdbc:presto: prefix and parses the remainder as a URI; a URISyntaxException (malformed URL, illegal characters) is converted to this SQLException carrying the offending URL, so the driver fails fast on unparseable connection strings.

Solutions

1. Fix the JDBC URL syntax, e.g. jdbc:presto://host:port/catalog/schema
2. URL-encode illegal characters (spaces, unescaped delimiters) in the URL
