Downloading and building PIO is not sufficient to run it. You must also install all of it’s dependencies, services like Spark, HDFS, …
The last concrete issue I saw from you was HDFS not running. PIO requires that HDFS is running as well as the other services before you can start it.
Go back and check that each service required is running correctly before trying to do anything with PIO. And remember that pio-start-all only starts some services so I don’t rely on it. Start the services you need by hand, verfiy they are working then start the pio EventServer. Continue from there.
At this point it might be better to wipe the machine and start over following only one set of instructions. Stick with that one since there are so many ways to configure PIO that switching between 2 install instructions will only confuse things.

Can you explain how you installed and what your problem is? The link below doesn’t contain much information.

Are you running the `pio` command from the `bin/` directory inside your fresh PredictionIO?
I've seen folks add "PredictionIO-dist/bin/" to their $PATH, so running `pio` is a simple command. This technique can go stale and cause these errors.

I've seen this error occur when an old `pio` command is used with a newer
install of PredictionIO.
Are you running the `pio` command from the `bin/` directory inside your
fresh PredictionIO?
I've seen folks add "PredictionIO-dist/bin/" to their $PATH, so running
`pio` is a simple command. This technique can go stale and cause these
errors.
