------------------------------

Am I missing something?  You remove the getScanner(scan, columns) in the patch, the thing you would seem to want to preserve going by your comment above.

> Currently when a {{StoreScanner}} is instantiated we use a {{getScanner(scan, columns)}} call that looks at things like bloom filters and memstore only flags.  But when we get a changed readers notification, we use {{getScanner()}} which just grabs everything.
> We should always use the original file selection algorithm.
