Hi!

Im a new user of PredictionIO trying to deploy some classification
template.

My prerequisites versions are

Apache Spark - 2.3.0
Scala - 2.11.8
Java SE Development Kit 8

i am using Postgresql

I have downloaded Classification template ,created app and collected data
as per documentation.
Now when i run the command "*pio build"  *These are the errors i get when
running from MyClassification directory

[root@abc PredictionIO-0.12.1]# cd MyClassification/
[root@abc MyClassification]# pio build
