   > RegionInfoBuilder and RegionInfo deeply reference each other, even if you remove the FIRST_META_REGIONINFO, there are lots of methods which return value or parameters are RegionInfo, and the MutableRegionInfo is a sub class of RegionInfo, and also a ineer class of RegionInfoBuilder...
   
   Right. This patch just reduces the window and chance of init race. If we see the jstacks (and see all the places that got changed in the patch), FIRST_META_REGIONINFO is touched in many init code paths and can potentially cause these races. The whole dependency system is still fragile and as you said, the proper way is to decouple them and I think that would be a much bigger refactor given the static fields are sprinkled all over the place and some of those places are IA.Public.
