Description

An alternative means of accessing hive tables is for the user to use hcatalog as the keyword eg: table default.customers will be accessed as hcatalog.default.customers.
The end user must not be aware of the underlying catalog store and should instead only be aware of hive/hbase/hdfs.
The above table can instead be accessed via hive.default.customers.
This allows us to expand this approach to also work with other datasources once schema auto discovery is complete HAWQ-450 and HAWQ-500
A file on HBase can be accessed using hbase.<tablename>
