In record reader level you can pass the file name as key or value.
sc.newAPIHadoopRDD(job.getConfiguration,
classOf[AvroKeyInputFormat[myObject]],
classOf[AvroKey[myObject]],
classOf[Text] // can contain your file)
AvroKeyInputFormat extends InputFormat<AvroKey[myObject], Text>
{
cretaRecordReader(){ return new YourRecordReader()}
}
YourRecordReader extends RecordReader<AvroKey[myObject], Text>{
initialize(){
Path file = inputSplit.getPath() ; // you can pass this file as a value
from your record reader
}
}
