Yang Wang created YARN-6589:
-------------------------------
Summary: Recover all resources when NM restart
Key: YARN-6589
URL: https://issues.apache.org/jira/browse/YARN-6589
Project: Hadoop YARN
Issue Type: Bug
Reporter: Yang Wang
When NM restart, containers will be recovered. However, only memory and vcores
in capability have been recovered. All resources need to be recovered.
{code:title=ContainerImpl.java}
// resource capability had been updated before NM was down
this.resource = Resource.newInstance(recoveredCapability.getMemorySize(),
recoveredCapability.getVirtualCores());
{code}
It should be like this.
{code:title=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);
{code}
