MENG DING commented on YARN-1651:
---------------------------------
Hi, [~leftnoteasy]
One comment I forgot to post is that we may want to synchronize the
RMContainerImpl.getAllocatedResource() call? Because the container resource may
be updated at any time, e.g:
{code:title=RMContainerImpl.java}
@Override
public Resource getAllocatedResource() {
- return container.getResource();
+ try {
+ readLock.lock();
+ return Resources.clone(container.getResource());
+ } finally {
+ readLock.unlock();
+ }
}
{code}
> CapacityScheduler side changes to support increase/decrease container
> resource.
