> This is a large-ish change to the HBase book
> - moving the 'data model' section forward in the book (before schema design)
> - adding some short API example snippets in 'data model' that illustrate the points discussed
> - correcting a minor formatting issue in my last patch with pre-creating regions.
> - included a listing of the region-server metrics
> ** however, I would like a one of the commiters to comment on what some of these are.
> - Expanded MapReduce example
> -- added a few short example snippets
> - Expanded the performance section
> -- some of which was simply referencing other configuration topics brought up elsewhere
that are certain to cause people performance problems if mis-configured.
> -- a few client examples of things that can cause performance problems if not used properly.
