"pio train" - Error: Could not find or load main class org.apache.spark.launcher.Main

[Patrick Zheng]

Hi,

I'm working with the latest ActionML's PredictionIO V0.9.7-Aml.

When I do "pio train", such error comes out at last,

Error: Could not find or load main class org.apache.spark.launcher.Main

I'm quite new on Spark. Would anybody give me some advice?

Thanks a lot!

Did you add a vendors folder and download + unpacked:  http://d3kbcqa49mib13.cloudfront.net/spark-1.5.1-bin-hadoop2.6.tgz as per: http://docs.prediction.io/install/install-linux/

The PIO doc site is out of date and should be avoided. It is being re-booted in Apache right now but until it’s live rely on actionml.com/docs

You have an incorrect installation. Start at actionml.com/docs/install
