> I have a server with two GPU, and i want to use only one of them within yarn
> cluster.
> according to hadoop document, i set configs:
> {code:java}
> <property>
> <name>yarn.nodemanager.resource-plugins.gpu.allowed-gpu-devices</name>
> <value>0:1</value>
> </property>
> <property>
>
> <name>yarn.nodemanager.resource-plugins.gpu.path-to-discovery-executables</name>
> <value>/etc/alternatives/x86_64-linux-gnu_nvidia_smi</value>
> </property>
> {code}
> then i running following command to test:
> {code:java}
> yarn jar
> ./share/hadoop/yarn/hadoop-yarn-applications-distributedshell-3.2.1.jar \
> -jar
> ./share/hadoop/yarn/hadoop-yarn-applications-distributedshell-3.2.1.jar
> -shell_command ' nvidia-smi & sleep 3 ' \
> -container_resources memory-mb=3072,vcores=1,yarn.io/gpu=1 \
> -num_containers 1 -queue yufei -node_label_expression slaves
> {code}
> iI expected gpu with minor number 0 will not visible to container, but in the
> launched container, nvidia-smi print two gpu information.
> I check the related source code and find it is a bug.
> the problem is:
> when you specify allowed-gpu-devices, GpuDiscoverer will populate usable gpus
> from it,
> then when assign to a container some of the gpus, it will set denied gpus for
> the container,
> but it never consider excluded gpu of the host.
