Wangda Tan commented on YARN-6620:
----------------------------------
[~jhung], thanks for reporting this.
I think the parsing logic should be changed since we want to support namespace
concept in resource name. Please file a bug under YARN-7069 accordingly.
I haven't tried to use node-resources.xml to set GPU configs before. The way
works for me is to set {{YarnConfiguration.NM_GPU_ALLOWED_DEVICES}} to allowed
devices (such as {{0,1,2,3}}) or {{auto}} so NM can discover it automatically.
Inside {{NodeStatusUpdaterImpl#serviceInit}}, it calls
{{updateConfiguredResourcesViaPlugins}} to overwrite {{totalResources}} after
loading from node-resources.xml.
> Add support in NodeManager to isolate GPU devices by using CGroups
