[jira] [Commented] (TAJO-336) Separate catalog stores into separate modules

["Hyunsik Choi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TAJO-336?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13842854#comment-13842854 ] 

Hyunsik Choi commented on TAJO-336:
-----------------------------------

Nice job! 

In addition, I would like to give additional suggestions for better packaging. 

* In my view, the name 'tajo-hive' is too general.
* We should use maven profile to enable only necessary drivers.
 ** Tajo can have many catalog store drivers, and the drivers can conflict to one another.
* We should allow 'mvn package -Ddist' to package enabled drivers.
 ** Otherwise, users should directly handle dependencies of certain drivers.

If the above suggestions are burden to you. I can take this work. Thanks!

> Catalog stores, such as HCatalogStore, involves dependencies to other systems. Their dependencies may be conflict from Tajo's dependencies because the dependent library versions can be varied in many cases.
> As to this problem, separating catalog stores from catalog-server module would be a good solution.
