Subject [jira] [Commented] (HIVE-3017) HIVE-2646 added Serde classes to hive-exec jar, duplicating hive-serde
Date Thu, 05 Jul 2012 22:02:34 GMT

    [ https://issues.apache.org/jira/browse/HIVE-3017?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13407529#comment-13407529
] 

Jakob Homan commented on HIVE-3017:
-----------------------------------

Something this bad should be fixed. It's particularly vexing when trying to develop against
Hive and needing to update two jars for one class.  Fat-jarring (which this esesentially is)
is evil. If the intention is to provide a convenient package for deployment, can't that be
done in maven by declaring a meta project with the other jars?

> Was this intentional? If so, the serde jar should be deprecated. If not, the serde classes
should be removed since this creates two sources of truth for them and can cause other problems
(see HCATALOG-407).
