Get stuck on creating new predictionio app

Question

I'm creating new predictionio app with below command:

pio app new test5

and just get stuck at below logs:

[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 figure it out?

have you read the google group posts regarding similar issues? here and here – Lever

Answer 1

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

Use this pio app new your_app_name --access-key your_key

I also met this problem.

You can use jstack -l <pid> to see what pio doing, in my case

so I think it's hang in get random.

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

My solution is flood ping sudo ping -f 10.10.255.1.
