I expected this to be the case, but looks like it isn't.

There's lot of value in splitting the HDFS code into smaller modules. Definitely newer code
like Ozone.

When we did this for YARN, initially there were concerns about module proliferation, but looking
back, my observations have been that it has done us far more good than expected. Starting
with the fact that we had clients and servers modularized independently, as well as servers
from other servers, with far cleaner contracts than what we had in Hadoop 1 world.

Thanks
