> For tools like pig and hive, blindly appending the full output of `bin/hbase classpath` to their own CLASSPATH is excessive. They already build CLASSPATH entries for hadoop. All they need from us is the delta entries, the dependencies we require w/o hadoop and all of it's transitive deps. This is also a kindness for Windows, where there's a shorter limit on the length of commandline arguments.
