Shall we add either the data source options map or the Hadoop conf as an
argument of this method?
For example, the Avro data source may filter out all input files whose file
names don't end with ".avro" if Hadoop conf
"avro.mapred.ignore.inputs.without.extension" is set to true. This is
consistent with default behavior of `AvroInputFormat`.
