Luke Lu commented on MAPREDUCE-2600:
------------------------------------
bq. I don't see how it makes development easier or faster to have lots of
little directories.
Smaller module means smaller code base to start for a typical feature and much
faster to recompile if one doesn't use an IDE. i.e, just mvn clean install in
the module directory. yarn only have 5 modules (including an integration test
module), the mapreduce runtime has 6 modules. Is this "lots of little
directories" that's out of control?
