Do not use `pio template get` it is being deprecated. Just use git like this:
git clone https://github.com/actionml/universal-recommender.git ur
cd ur
# edit engine.json to meet your needs, start from engine.json.minimum not
engine.json, which is for the integration tests.
pio build
If you are using the docker container mentioned below we cannot guarantee it is
correct and do not support it. See the maintainer for questions about it’s use.

Thats why i opted for other template which i mentioned before. I was not able
to find much on this error.
Sir i wanted to ask one more question how to run pio build behind a proxy
server with authentication

That is an old template that does not work with Apache PIO
Look on the Apache PIO template gallery for compatible templates including this
one: https://github.com/actionml/universal-recommender
<https://github.com/actionml/universal-recommender>
I can’t understand how the old one got through `pio build` with Apache PIO
0.10.0. Something is not right in the docker image you mention, if the template
you linked to runs. the docker image must use the old Prediction.io
<http://prediction.io/> from before moving to Apache

The template i m using sir is this template
<https://github.com/PredictionIO/template-scala-parallel-universal-recommendation>Sir
i m using docker image of predictionio. The docker image is
steveny/predictionio/ <https://hub.docker.com/r/steveny/predictionio/>.
The predictionio version is 0.10.0
Apache spark version is 1.5.1
One thing sir i would like to mention is that it is running fine for small
datasets but on using a largedataset i m facing this issue
Sir i googled this error one of the fixes available was to upgrade the spark
version to 1.6
And the other fix is in this link stackoverflow
<http://stackoverflow.com/questions/32667068/save-spark-dataframe-into-elasticsearch-can-t-handle-type-exception>.
I am unable to understand where(i mean which files) i have to add the said
classes in the link.
Sir i am also unable to understand how to upgrade spark in the docker image.

Can you give more of the stack trace? I assume you are running the UR, which
version and what version of PIO?
Off hand it looks like a problem with installation of Spark. What version of
that do you have?
