Hi,  Khan:
    I have some questions for your design:
    1. It looks like the the following comamd is supported by spark(hive).

CREATE (DATABASE|SCHEMA) [IF NOT EXISTS] database_name[COMMENT 'database_comment']   [LOCATION hdfs_path];
    2. For spark and hive, the default tablePath is `tablePath = databaseLocation + "/" + tableName`， I think keep the default behavior is better.
    For Backward Compatibility, we also support
    tablePath = carbon.storeLocation + “/” + database_Name +”/”  + tableName
   

    3. What does `Carbon.update.sync.folder` means?
