Before you start, send a message to the Tajo developer mailing list (firstname.lastname@example.org), or file a bug report in Tajo Jira. Describe your proposed changes and check that they fit in with what others are doing and have planned for the project. Be patient, it may take folks a while to understand your requirements. Modify the source code and add some (very) nice features using your favorite IDE.
