Subject [jira] [Commented] (YARN-9217) Nodemanager will fail to start if GPU is misconfigured on the node or GPU drivers missing
Date Thu, 07 Feb 2019 13:50:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-9217?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16762687#comment-16762687

Antal Bálint Steinbach commented on YARN-9217:

Hi [~snemeth] ,

Thanks for the review. A new patch is created to address your comments and checkstyle issues.

I agree I cannot see any reason for the "smart" error handling in the NM Web API. I moved
it to the plugin because it is used only in the plugin, so it will not affect other GpuDiscoverer

> Nodemanager will not start
> 1. If Autodiscovery is enabled:
>  * If nvidia-smi path is misconfigured or the file does not exist.
>  * There is 0 GPU found
>  * If the file exists but it is not pointing to an nvidia-smi
>  * if the binary is ok but there is an IOException
> 2. If the manually configured GPU devices are misconfigured
>  * Any index:minor number format failure will cause a problem
>  * 0 configured device will cause a problem
>  * NumberFormatException is not handled
> It would be a better option to add warnings about the configuration, set 0 available
GPUs and let the node work and run non-gpu jobs.
