PLATFORM_FAILURE

How to reproduce it:
submit a new job.

OpenPAI Environment:

• OpenPAI version: v1.8.0

• Cloud provider or hardware configuration:

• OS (e.g. from /etc/os-release):

• Kernel (e.g. uname -a): Linux rsgpuserver154 4.15.0-166-generic 174-Ubuntu SMP Wed Dec 8 19:07:44 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

• Others:

Anything else we need to know:

Start with docs/user/troubleshooting_job.md and the job-debugging section of docs/job_tutorial.md, then reproduce the failure by submitting a new job. Use the reported pod diagnostics, especially the app container's exit message, to identify the cause; done means documenting or fixing the confirmed cause and verifying that a job submits successfully.
