@pferrel For `pio build` we probably can enhance it such that it can take a
working directory for compilation to run. If we look at some other build tools,
they also rely on having certain files in the current working directory.
For `pio train` and `pio deploy`, I absolutely agree that it should be able
to run from anywhere as the most advanced scenario. My personal take to this
change would be something comparable to a local HBase and distributed HBase
setup. It would be ideal if someone can start playing with PredictionIO without
setting up any external services (not even a SQL database). I believe Chan's
change here is a partial step to make the learning curve less steep, and path
ways for us to untangle engine registration so that it could become a feature
that can be more easily documented and understandable.
Do you currently have any production deployments that rely heavily on
engine IDs and versions? That would be a bigger immediate concern regarding
this change.
