Is it possible for the record reader to get a copy of the job configuration or is it otherwise possible to send configuration values to the record reader?
Yes. Typically InputFormat.getRecordReader instantiates the RecordReader; and that function is passed the JobConf. So you could pass it down from there-on.
Take a look at SequenceFileRecordReader.java or LineRecordReader.java in trunk/src/java/org/apache/hadoop/mapred for an example.
