A good friend recommended another client tool that we can use to access the Vertica database. I've been using it for a few days and like it a lot.
Check it out!

Excerpt from their web page:
SQL Workbench/J is a free, DBMS-independent, cross-platform SQL query tool. It is written in Java and thus it should run on any operating system that provides a Java Runtime Environment.
It's main focus is on running SQL scripts (either interactively or as a batch) and export/import features. Graphical query building or more advanced DBA tasks are not the focus and are not planned
