> Profiling I actually ran into case where complaint that could not inline
> because:
> MaxInlineLevel maximum number of nested calls that are inlined 9 intx
> i.e. method was more than 9 levels deep.
> The HFileReaderV? with Abstracts is not needed anymore now we are into the
> clear with V3 enabled since hbase 1.0.0; we can have just an Interface and an
> implementation. If we need to support a new hfile type, can hopefully do it
> in a backward compatible way now we have Cell Interface, etc.
> Squashing all this stuff together actually makes it easier figuring what is
> going on when reading code. I can also get rid of a bunch of duplication too.
> Attached is a WIP. Doesn't fully compile yet but you get the idea.
> I'll keep on unless objection. Will try it against data written with old
> classes as soon as I have something working. I don't believe we write
> classnames into our data.
