> This initial patch has several important features:
> # HBaseStore, a new implementation of RawStore that stores the data in HBase.
> # Subclasses of the thrift metastore objects to remove the massive duplication of data
where every partition contains a nearly identical storage descriptor.
> # Caches for catalog objects and statistics so that repeated metastore calls don't result
in repeated calls against HBase.
> Currently this "works" to the point that "load table" and "select" work.  I have not
tested any other statements, and I suspect most fail.  There is no security, no authorization,
and a no a lot of other things.
