> We have some optional build components which don't get built if they are not installed
on the build machine.  One of those components is fuse_dfs.  Another is the snappy support
in libhadoop.so.
> Unfortunately, since these components are silently ignored if they are not present, it's
easy to unintentionally create an incomplete build.
> We should add two flags, -Drequire.fuse and -Drequire.snappy, that do exactly what the
names suggest.  This will make the build more repeatable.  Those who want a complete build
can specify these system properties to maven.  If the build cannot be created as requested,
it will be a hard error.
