Pin when creating a new predictionio application

I am creating a new forecasting application with the following command:

pio app new test5

and just stuck in lowercase:

 [INFO] [HBLEvents] The table pio_event:events_5 doesn't exist yet. Creating now... [INFO] [App$] Initialized Event Store for this app ID: 5. stuck here..

how to understand this?

The root cause of this is related to the implementation of OS access key generation.

Use pio app new your_app_name --access-key your_key

I also met this problem.

You can use jstack -l <pid> to find out what pio does, in my case

so I think it freezes up by accident.

Then I check /proc/sys/kernel/random/entropy_avail , it is very small.

My solution is ping ping sudo ping -f 10.10.255.1 .
