When you use tTeradataFastExport in 188.8.131.5270510_1410 if there is already a file created when you run the job you will get the error:
java.lang.RuntimeException: The particular file "C:\2017-11-17.csv" already exist. If you want to overwrite the file, please uncheck the "Throw an error if the file already exist" option in Advanced settings.
The problem is the option doesn't exist in advanced settings of the tTeradataFastExport component:
Could you please create a new feature jira issue on talend bug tracker?
