Missing libs, so we can run straight from local.

Downgrade libprotobuf to 2.4.0a.

Hadoop is on 2.4, and they haven't hidden the lib 
using jar jar.

Now, we are using jarjar, but if we hide our
protobuf, the hadoop client libs will fail, 
so that's not an option.
Introduce HadoopPipelineTest.

Test works, counts words in Hadoop.


Fixed silly bugs in the pipeline.

TableAdmin now creates non-self-destructive tables.
