Binglin Chang commented on YARN-2088:
-------------------------------------
Based on recent bugs related to api records/PBImpl, I have some doubts about
the general patterns used in PBImpls(java fields mixed with proto objects,
cached states), which causes lots of redundant code and confusion, changes to
those code is a mental challenge and can easily generate new bugs...
> Fix code bug in GetApplicationsRequestPBImpl#mergeLocalToBuilder

> Some fields(set,list) are added to proto builders many times, we need to
> clear those fields before add, otherwise the result proto contains more
> contents.
