JDBC connection should catch malformed URLs better
--------------------------------------------------
Key: CASSANDRA-2859
URL: https://issues.apache.org/jira/browse/CASSANDRA-2859
Project: Cassandra
Issue Type: Improvement
Components: Drivers
Reporter: Jonathan Ellis
Assignee: Jonathan Ellis
Some problems with the current connection handing:
- host-less URLs are assumed to be localhost, when this is more commonly the
result of a malformed URL (exhibit A: the current JdbcDriverTest connection)
- there is no standard syntax for user/password in the url; attempting to
support this will result in more malformed URLs. most (all?) other JDBC
drivers force you to use the user/pass or properties constructors instead.
- finally, a malformed URL can result in a very confusing
InvalidRequestException if you manage to end up with garbage in the "path"
component (which becomes keyspace): we send USE X to the server and if there
are non-alphanumeric characters there we will get back a cryptic antlr parse
failure ("line 1:28 no viable alternative at character 'K'")
