>
> If a sequence file contains MapWritable objects, running "hadoop fs -text" on
> the file prints the following for each MapWritable:
> org.apache.hadoop.io.MapWritable@4f8235ed
> To be more useful, it should print out the contents of the map instead. This
> can be done by adding a toString method to MapWritable, i.e. something like:
> public String toString() {
> return (new TreeMap<Writable, Writable>(instance)).toString();
> }
