-----------------------------------

             Summary: Refactor MetaStoreDirectSql by using getProductName instead of querying
DB to determine DbType
                 Key: HIVE-9741
                 URL: https://issues.apache.org/jira/browse/HIVE-9741
             Project: Hive
          Issue Type: Bug
          Components: Metastore
    Affects Versions: 1.0.0
            Reporter: Xiaobing Zhou
            Assignee: Xiaobing Zhou
         Attachments: HIVE-9741.1.patch

MetaStoreDirectSql constructor is querying DB to determine dbType. which leads to too many
DB queries to make metastore slow or hanging if MetaStoreDirectSql constructor is frequently
called. This is to propose getProductName to get dbType info.
