Subject [jira] [Created] (YARN-9370) Better logging in recoverAssignedGpus in class GpuResourceAllocator
Date Fri, 08 Mar 2019 14:16:00 GMT
Szilard Nemeth created YARN-9370:

             Summary: Better logging in recoverAssignedGpus in class GpuResourceAllocator
                 Key: YARN-9370
                 URL: https://issues.apache.org/jira/browse/YARN-9370
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Szilard Nemeth

The last line of org.apache.hadoop.yarn.server.nodemanager.containermanager.linux.resources.gpu.GpuResourceAllocator#recoverAssignedGpus
is this: 

usedDevices.put(gpuDevice, containerId);
We should have an info (or if not info, at least a debug) level log to indicate that a container
is allocated to a GPU device during recovery. 
Please also check recovery related code, maybe there can be some room for improvement around
