public class AvroAsTextInputFormat extends FileInputFormat<Text,Text>
InputFormat for Avro data files, which
converts each datum to string form in the input key. The input value is
always empty. The string representation is
JSON.
This InputFormat is useful for applications
that wish to process Avro data using tools like MapReduce Streaming.
By default, when pointed at a directory, this will silently skip over any
files in it that do not have .avro extension. To instead include all files,
set the avro.mapred.ignore.inputs.without.extension property to false.
