[jira] [Created] (TAJO-298) Catalog Federation

JaeHwa Jung created TAJO-298:
--------------------------------

             Summary: Catalog Federation
                 Key: TAJO-298
                 URL: https://issues.apache.org/jira/browse/TAJO-298
             Project: Tajo
          Issue Type: Improvement
          Components: catalog
    Affects Versions: 0.8-incubating
            Reporter: JaeHwa Jung
            Assignee: JaeHwa Jung
             Fix For: 0.8-incubating


Current Catalog supports just one Catalog server. But I think that users want to use serveral tables stored of multiple Catalogs at the same time. For example, After user query hive tables, user can inserver into tajo table. Above this, many use cases will happen. So, I wish that tajo supports muliple Catalog named Catalog Ferderation. I was inspired from HDFS Ferderation.
