Now the compare code is : return a1.getApplicationId().getId() - a2.getApplicationId().getId(); Will be replaced with : return a1.getApplicationId().compareTo(a2.getApplicationId()); This will bring some benefits: 1,leave applicationId compare logic to ApplicationId class; 2,In future's HA mode,cluster time stamp may change,ApplicationId class already takes care of this condition. -- This message is automatically generated by JIRA.
