> HConnectionManager uses deprecated HServerAddress to create server cache key which needs to resolve the address every time.
> It should be better to use HRegionLocation.getHostnamePort() instead.
> In our cluster we have some DNS issue, resolving an address fails sometime which kills the application since it is a runtime
> exception IllegalArgumentException thrown at HServerAddress.getResolvedAddress.  This change will fix this issue as well.
