Minor Description
After REEF-414 we still have around 50 checkstyle violations in "Naming" category which involve public fields/methods. We can't fix them immediately, as this could potentially break public interfaces. Instead we have to
1) Create properly names fields/methods which duplicate existing ones
2) Mark existing fields/methods as deprecated and add checkstyle exceptions to them individually
3) Convert all checks in "Naming" to error-level, so that no new violations are introduced
4) (in next release) Remove deprecated fields/methods and exceptions for them
