Subject Error in getting Total Events in a predictionIo App
Date Tue, 14 Nov 2017 14:39:41 GMT
Hi , 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 inorder to verify the count of imported events .I ran the
following commands

 1. pio-shell --with-spark
 2. import org.apache.predictionio.data.store.PEventStore
 3. val eventsRDD = PEventStore.find(appName="testApp")(sc)

I got the error:

    ERROR Storage$: Error initializing storage client for source

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.
