> Here is comment from Lars (HBASE-2195):
> When we did versioning for a project I used to work on a long time ago, we had maintained a class version *and* an instance version. We might need both.
> The class should know which version it is, but also it is useful in many scenarios to ask the instance what specific version it is on.
> I.e. we need an interface with two methods: One to get the class version, one to get the instance version.
> This would apply to HLogKey which is able to read entries without explicit version.
