Option 1 is indeed the most adapted (remember the issue on small files 
stored in hdfs).

You could even start without worrying about splitting in chunks to begin.

There was a discussion on the hbase mailing list about this a month ago 
(or so), and a generic solution could even be used in a short time frame.

If we don't have that generic solution, we can implement ours during the 
"optimization" phase.

Sounds like we putting much in that "optimization" phase, but it's how 
iterative development works with constant refactoring. You can also 
think to "test driven development" and have the needed unit tests that 
ensure that your refactoring does not break anything.
