]

LongGang Chen updated YARN-8353:
--------------------------------
    Description: 
LightWeightResource's hashCode function is different from parent class.

One of the consequences is: 

ContainerUpdateContext.removeFromOutstandingUpdate will nor work correct,

ContainerUpdateContext.outstandingIncreases will has smelly datas.

a simple test:
public void testHashCode() throws Exception {
    Resource resource = Resources.createResource(10,10);  
    Resource resource1 = new ResourcePBImpl();  
    resource1.setMemorySize(10L);    
    resource1.setVirtualCores(10);  
    int x = resource.hashCode();  
    int y = resource1.hashCode();  
    Assert.assertEquals(x, y);  
}
