-Initialization for record writing.
Jane Chen 2011-01-21, 23:57
Looking at 0.21's API,
In org.apache.hadoop.mapreduce.RecordReader, there is an initialize() method that I can use for one time work;
In org.apache.hadoop.mapreduce.RecordWriter, there is no initialize().
Why is that? Where am I supposed to do the one time initialization? In the constructor? Why the asymmetry?
