Why no DoubleWritable?

[Jimmy Lin <ji...@umd.edu>]

Hi guys,

What's the design decision for not implementing a DoubleWritable type
that implements WritableComparable? I noticed that there are classes
corresponding to all Java primitives except for double.

Thanks in advance,
Jimmy

Hi,

The reason may be that perhaps nobody needed the extra precision brought 
by double compansating the extra space, compared to FloatWritable. If 
you really need DoubleWritable you may write the class, which will be 
straightforward, and then attach it to a jira issue so that we can add 
it to the core. That's the way open sourse works after all. *smile*
