Facing same issue with Digitalocean 4GB Ram PredictionIO-0.9.6. Unable to create a new app.
It just hangs.

Hi, Aaron.
I have the same issue with Digital Ocean and PredictionIO-0.9.6.
So, have you manage it?

Hello -

I am having very similar symptoms as referenced in this post:!searchin/predictionio-user/Initialized$20Event$20Store$20for$20this$20app/predictionio-user/LLAHhfS6hk8/Gz5SqMV0DQAJ

- I had a digital ocean box running PIO successfully with version 0.9.4. 
- I wanted to use the new version of the universal recommender, which requires pio 0.9.5 plus,
so I did a fresh install of pio (rm -l'ed the directory and fresh install)
- when trying to create a new app now of the universal recommender engine, it hangs after
the pio app new <app name> command (never returns anything)

Exact steps:
I have created about 10 new VMs trying to follow the quick setup guide very explicitly, but
I always get the same results. The steps are

1 install java 8
 $ sudo add-apt-repository ppa:webupd8team/java
 $ sudo apt-get update
 $ sudo apt-get install oracle-java8-installer
 $ sudo apt-get install oracle-java8-unlimited-jce-policy

2. install predictionIO
sudo bash -c "$(curl -s <>)"

3 restart machine
a. shutdown -h now
b. go to droplet and power on

4 Start predictionIO

5. create engine directory
mkdir ~/engines

6. download engine
example: pio template get PredictionIO/template-scala-parallel-universal-recommendation <YourNewEngineDir>
pio template get PredictionIO/template-scala-parallel-universal-recommendation ~/engines/test

6. create app
examples: pio app new handmade

I have an image of the pio 9.4 install and it works correctly, but the same exact host / size
/ ram ect except for pio version 9.6 fails. 

Anyone have any suggestions?
