Jake Mannix commented on MAHOUT-874:
------------------------------------
The *Writables depend on very little other than core Mahout classes (internal)
and Hadoop. The runtime jarhell is completely minimized. Look at the list of
dependencies the *Writables would depend on compared to the mahout-core package.
Just as mahout-math is totally "core" to what we do, it's still really nice
that it's in its own jar with very minimal external dependencies.
mahout-writables *could* be equally slim and non-dependent, and allow for a jar
which lets people read/write wire-compatible data with us without depending on
everything that mahout-core pulls in.
Re: Progaurd I don't think I have much say in changing the way our build system
works. We use ivy, and I can depend on stuff from maven repos, and put in
exclude statements, but that's about it. This is very similar to other places
I've worked, as this is a pretty common issue.
