             Fix For: 2.0.0-beta-1


Reported by [~psomogyi] up on HBASE-19295, the issue that added CpEnv returning 
a read-only Configuration.

Issue is that hadoop Configuration registers every created Configuration in a 
static REGISTRY on construction. A call to addDefaultResource -- e.g. sqoop 
does this in tests to get its configurations into the mix -- results in a call 
to every registered Configurations loadResource.. which is disallowed in our 
read-only Configuration.
