> There are a bunch of places in the code like this:
> region.close();
> region.getLog().closeAndDelete();
> Instead of the better:
> HRegion.closeHRegion(region);
> We should change these for a few reasons:
> 1) If we ever need to change the implementation, it's easier to change in one place
> 2) closeHRegion properly checks for nulls.  There are a few places where this could make a difference, for example in TestOpenedRegionHandler.java it's possible that an exception can be thrown before "region" is assigned and thus region.close() could throw an NPE.  closeHRegion avoids this issue.
