Subject [jira] [Commented] (YARN-9235) If linux container executor is not set for a GPU cluster GpuResourceHandlerImpl is not initialized and NPE is thrown
Date Thu, 28 Mar 2019 12:32:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-9235?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16803882#comment-16803882

Antal Bálint Steinbach commented on YARN-9235:
----------------------------------------------

Hi,

LOGGER is renamed to LOG.

I agree that testing general exceptions need to be checked, but testing its error message
is not the way to do that for several reasons. (parameters in the text, i18n, etc..)

I do not want to change the exception itself, as this was a small refactor and NPE fix. So
I think this small tradeoff is acceptable in the test.

[~sunilg], [~tangzhankun] can you please push?

> If GPU plugin is enabled for the NodeManager, it is possible to run jobs with GPU.
> However, if LinuxContainerExecutor is not configured, an NPE is thrown when calling 
> {code:java}
> GpuResourcePlugin.getNMResourceInfo{code}
> Also, there are no warns in the log if GPU is misconfigured like this.
