Subject Re: Empty result even though there are events
Date Mon, 03 Apr 2017 04:06:32 GMT
Hi,

Thank you, I did the changes. But whenever I changed the appname and did
pio build its Ok, but while training it says invalid appname for any other
app name. I'm missing something, however when I left the appname as
handmade, it works.

Now the data and recommendation are all working. Thank you very much, I
used engine.json.minimum. I will be testing other features, like cart
recommendation. Here's my engine.json

{
  "comment":" This config file uses default settings for all but the
required values see README.md for docs",
  "id": "default",
  "description": "Default settings",
  "engineFactory": "org.template.RecommendationEngine",
  "datasource": {
    "params" : {
      "name": "sample-handmade-data.txt",
      "appName": "handmade",
      "eventNames": ["purchase", "view"]
    }
  },
  "sparkConf": {
    "spark.serializer": "org.apache.spark.serializer.KryoSerializer",
    "spark.kryo.registrator":
"org.apache.mahout.sparkbindings.io.MahoutKryoRegistrator",
    "spark.kryo.referenceTracking": "false",
    "spark.kryoserializer.buffer.mb": "300",
    "spark.kryoserializer.buffer": "300m",
    "es.index.auto.create": "true"
  },
  "algorithms": [
    {
      "comment": "simplest setup where all values are default, popularity
based backfill, must add eventsNames",
      "name": "ur",
      "params": {
        "appName": "handmade",
        "indexName": "urindex",
        "typeName": "items",
        "comment": "must have data for the first event or the model will
not build, other events are optional",
        "eventNames": ["purchase", "view"]
      }
    }
  ]
}

I was very curious, what does this means: "name":
"sample-handmade-data.txt",
Thanks
