Harness doesn't create ES Index

When I want to create an Engine from my engine-template, Harness doesnt create an Index in Elasticsearch. Does anyone know why?

My sample engin.json looks like

{
	"engineId": "ecommerce",
	"engineFactory": "com.actionml.engines.ur.UREngine",
	"sparkConf": {
		"master": "local",
		"spark.driver-memory": "8g",
		"spark.executor-memory": "16g",
		"spark.serializer": "org.apache.spark.serializer.KryoSerializer",
		"spark.kryo.registrator": "org.apache.mahout.sparkbindings.io.MahoutKryoRegistrator",
		"spark.kryo.referenceTracking": "false",
		"spark.kryoserializer.buffer": "300m",
		"spark.es.index.auto.create": "true",
		"es.index.auto.create": "true"
	},
	"algorithm": {
		"indicators": [
			{
				"name": "buy"
			},
			{
				"name": "detail-view"
			},
			{
				"name": "search-terms"
			}
		]
	}
}

Further in the logs the output shows that ES index name: is null

@pferrel - i discovered the source of the issue i was having, and just neglected to update here, so here’s what was the problem. engine creation, and event adding was fine, and when I would call the “train” endpoint, that was failing, and I simply failed to notice that step was failing, so the training failed, thus no index was ever created and the queries obviously would fail.

the reason training was failing was that i didn’t have sample data for a few of the indicators. i feel like this should be allowed (no data for an indicator, so that training can complete) but i do understand it. i have since worked around this factor and am now seeing everything work correctly.

OK… It seems like I must first add event with primary indicator, and then train engine… on train it create index and everything start works 😉
