Tao Jie commented on YARN-5552:
-------------------------------
Rebased the patch.
And find out api records with quite a few properties and multiple newInstance methods to add builder：
Container, ApplicationReport, ContainerReport, GetApplicationsRequest

> Currently yarn API records such as ResourceRequest, AllocateRequest/Respone as well as AMRMClient.ContainerRequest have multiple constructors / newInstance methods. This makes it very difficult to add new fields to these records.
> It would probably be better if we had Builder classes for many of these records, which would make evolution of these records a bit easier.
