Hey Keneth

Thank for the answer.

After running „pio build“ i get the following error during the „pio train“ 
process:

[ERROR] [Executor] Exception in task 0.0 in stage 3.0 (TID 9)
[WARN] [TaskSetManager] Lost task 0.0 in stage 3.0 (TID 9, localhost):

Hello together,

I finally got the System running and would like to import some initial data now.

I’m using the E-Commerce-Template: 
http://predictionio.incubator.apache.org/templates/ecommercerecommendation/quickstart/

I've the following data’s i would like to import:

  *   User data

  *   Products data

  *   Transaction data

When i try to use the pio import --appid 1 --input import/data-user.json 
command i’m always getting an exception with the initial load from User & 
Product. My .json file is following the structure mentioned on the tutorial.


  *   For User Data: 
{"event":"$set","entityType":"user","entityId":"user001","eventTime":““}
  *   For Products  
{"event":"$set","entityType“:"item","entityId“:"product001","eventTime":““}

  *   For Transactions: 
{"entityId“:"user001","entityType":"user","event":"buy","targetEntityType":"item","targetEntityId“:"product001“}

Only the Import for Transactions is working I found this template here: 
https://gist.github.com/vaghawan/0a5fb8ddb85e03631dd500d7c8f0677d#file-data-sample-json

So my quesiton, how can I import Data’s like


  *   User Data
  *   User Categories
  *   Product Data
  *   Product Categories

with a .json file? What is the file structure?

Thanks for any help,
Sebastian
