参数:

failOnParseError - if set to true, parsing failure on any line will cause parsing to be terminated; when set to false, parsing failure on a given line will not prevent remaining lines from being parsed - this allows us to analyze fields, even if some field is mis-configured and causes a parsing error for the values of that field.
