Installing ActionML PIO + UR - HBase problem

After following instructions to install ActionML's PIO on a single server, I get this error:

Installing ActionML PIO + UR - surprise downloading dependency Scala jar

I'm following the upgrade document from http://www.actionml.com/docs/install to get ActionML installed/upgraded ( see previous posts ). When running ./make-distribution.sh I get this error:

I have a fast and reliable Internet connection here at the office. Retrying resolved the problem.

ActionML PredictionIO upgrade - tricky details

I'm trying to install ActionML PredictionIO and the Universal Recommender ( see previous posts ). Now I'm following the documentation to upgrade at http://www.actionml.com/docs/install .
Some tricky details:
  - The documentation has a step with sudo su aml that will switch to the aml user. Later on it has steps such as rm -r ~/.ivy2, but you should remember not to run as the aml user!

- The documentation tells you to run ./make-distribution but they meant ./make-distribution.sh instead.

PredictionIO: Upgrading or Installing?

  After installing ActionML's PredictionIO + Universal Recommender with the "quick install" methods failed, I'm told by someone in the discussion group that I must "upgrade". And so I go to
http://www.actionml.com/docs/install








It's not clear if this page is for installing fresh or upgrading. The page has an "Upagrade"  section and a "Install Fresh" section after, in the middle of the page.
