Error in getting Total Events in a PredictionIO App - apache-spark

Question

I am new to PredictionIO using version v0.11-incubating (spark - 2.6.1 , Hbase - 1.2.6 , ElasticSearch - 5.2.1) . Started the Prediction Server with ./pio-start-all and checked pio status these are working fine. Then I created an app 'testApp' and imported some events into that PredictionIO app. Now in order to verify the count of imported events, I ran the following commands:
pio-shell --with-spark
import org.apache.predictionio.data.store.PEventStore
val eventsRDD = PEventStore.find(appName="testApp")(sc)
I got the error:
ERROR Storage$: Error initializing storage client for source ELASTICSEARCH

I have verified through pio status and ElasticSearch health commands that the elastic search server is running. Can someone please tell me how to resolve this issue?

Answer 1

Resolved this issue by upgrading predictionIO version from 0.11.0 -> 0.12.0
