Subject [jira] [Updated] (YARN-9217) Nodemanager will fail to start if GPU is misconfigured on the node or GPU drivers missing
Date Wed, 06 Feb 2019 14:59:00 GMT

     [ https://issues.apache.org/jira/browse/YARN-9217?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Antal Bálint Steinbach updated YARN-9217:
-----------------------------------------
    Description: 
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.
