Map output files and partitions.

There only 2 types of map output files, Sequence and Text files. If
those files are going to be used as input to several reduce tasks,
they need to be partitioned into blocks. Is there any SEPARATOR bits
that limits each partition? Can I read a specific partition of a map
output file? Is there an API for that?

Best regards,
