Subject [jira] [Updated] (TAJO-289) CatalogDriver
Date Tue, 29 Oct 2013 03:19:38 GMT

JaeHwa Jung updated TAJO-289:
-----------------------------

    Description: 
I designed Tajo to use Hive metastore with HCatalog.
In this case, Tajo has to have an interface to connect to HCatalog.
And I think that this connect is very useful to connect to another catalogs as follows:
 some different Hive catalogs, HBase catalogs

So, I named this interface as CatalogDriver. It will has some properties as follows:
- catalog namespace name
- catalog URI
- catalog driver class

  was:
