--columnsHaveTypes                          indicated that the field list (from
                                                  --fields, --fieldsFile, or
                                                  --headerline) specifies types; They
                                                  must be in the form of
                                                  '<colName>.<type>(<arg>)'. The type can
                                                  be one of: auto, binary, bool, date,
                                                  date_go, date_ms, date_oracle, double,
                                                  int32, int64, string. For each of the
                                                  date types, the argument is a datetime
                                                  layout string. For the binary type, the
                                                  argument can be one of: base32, base64,
                                                  hex. All other types take an empty
                                                  argument. Only valid for CSV and TSV
                                                  imports. e.g. zipcode.string(),
                                                  thumbnail.binary(base64)
