stack updated HBASE-559:
------------------------
Attachment: 559.patch
First cut at a RowCounter class. Includes a 'Driver' class so we can plug in
other MR jobs. Need to hook this up as the Main-Class for the hbase jar so
hbase jar can be a hadoop job jar. Patch goes against branch for the moment
(Lars wants a sample and he's running branch).

> The Lars' import is a little messy; he's not sure how many records were
> imported. Running a select takes a couple of hours. He happens to have an
> idle MR cluster standing by. An example MR job that just did a count of
> records would be generally useful. Could even output row keys so you'd have
> a list of what made it in. Later, if this tool becomes popular with
> derivatives and similiars, we can bundle a jar of MR jobs to run against your
> tables that can answer common queries and that are amenable to
> subclassing/modification.
