>
> RawStore functions that support partition filtering are the following -
> getPartitionsByExpr
> getPartitionsByFilter (takes filter string as argument, used from hcatalog)
> We need to generate a query execution plan in terms of Hbase scan api calls
> for a given filter condition.
> NO PRECOMMIT TESTS
