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
