> Currently the jars are uploaded to either user directory or global, whatever is configured, which is a mess and can cause collisions. We can upload to scratch directory, and/or version. 
> There's a tradeoff between having to upload files every time (for example, for commonly used things like HBase input format) (which is what is done now, into global/user path), and having a mess of one-off custom jars and files, versioned, sitting in .hiveJars.
