## What changes were proposed in this pull request?

When zinc is running the pwd might be in the root of the project. A quick solution to this is to not go a level up incase we are in the root rather than root/core/. If we are in the root everything works fine, if we are in core add a script which goes and runs the level up

## How was this patch tested?

set -x in the SparkR install scripts.
