> {{CsvTableSink}} has supported {{writeMode}} which could be {{OVERWRITE}} or {{NO_OVERWRITE}}. When we execute "INSERT OVERWRITE csv_table_sink xx", planners will check whether a table sink is an {{OverwritableTableSink}}.
> Now {{CsvTableSink}} does not extend from {{OverwritableTableSink}}, so we can't execute above statement.
