> This is the basis for supporting equal-depth histograms per region, guideposts, -49.
> Its basically a 0.94 backport of the code attached to HBASE-7958. Logically, there is
> no real difference, though the implementation is has some slight changes as on trunk there
> is no need for a coprocessor as the stats gather is all built in.
> Currently, HBASE-7958 is stil open for review and depends on the the system tables (HBASE-7999) or
> namespaces (HBASE-8105) patches. We resolve this by just giving the stats table a special name
> that should be fairly close to the pending name for the stats table in HBASE-7958. In the event
> that we cannot maintain the same table name for the stats table, we do have an opportunity to
> copy over the data to the neew table as there is currently a required downtime to upgrade from 0.94
> to 0.96.
> This is actually a bit more advanced than the posted patch - a lot more work has gone into usability
> and verifying correctness. Further, there are some obvious changes as we need to support coprocessors
> rather than built options (but that is actually a relatively minor change).
