Description

When NM restart, containers will be recovered. However, only memory and vcores in capability have been recovered. All resources need to be recovered.

ContainerImpl.java

      // resource capability had been updated before NM was down
      this.resource = Resource.newInstance(recoveredCapability.getMemorySize(),
          recoveredCapability.getVirtualCores());

It should be like this.

ContainerImpl.java

      // resource capability had been updated before NM was down
      // need to recover all resources, not only <mem, vcores>
      this.resource = Resources.clone(recoveredCapability);
