Peter Bacsko commented on YARN-9120: ------------------------------------ Thanks for confirming it [~tangzhankun]. I'm confident that most clusters will be heterogeneous, so it's good to know that Ambari supports that. Regarding the "off" value, I'm not super-insistent on having it. After all, most users will probably use a GUI anyway and click on buttons to turn it on/off. > Need to have a way to turn off GPU auto-discovery in GpuDiscoverer > ------------------------------------------------------------------ > > Key: YARN-9120 > URL: https://issues.apache.org/jira/browse/YARN-9120 > Project: Hadoop YARN > Issue Type: Improvement > Reporter: Szilard Nemeth > Assignee: Szilard Nemeth > Priority: Major > > GpuDiscoverer.getGpusUsableByYarn either parses the user-defined GPU devices > or should have the value 'auto' (from property: > yarn.nodemanager.resource-plugins.gpu.allowed-gpu-devices) > In some circumstances, users would want to exclude a node from scheduling, so > they should have an option to turn off auto-discovery. > It's straightforward that this is possible by removing the GPU > resource-plugin from YARN's config along with GPU-related config in > container-executor.cfg, but doing that with a dedicated value for > yarn.nodemanager.resource-plugins.gpu.allowed-gpu-devices is a more > lightweight approach. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
