Subject [jira] [Commented] (HIVE-5380) Non-default OI constructors should be supported for backwards compatibility
Date Tue, 25 Feb 2014 08:47:19 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5380?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13911395#comment-13911395
] 

Lefty Leverenz commented on HIVE-5380:
--------------------------------------

[~lars_francke] identified the source of the exclamation point prefixes in the Hive SerDe
& Object Inspector sections of the Developer Guide:  old MoinMoin syntax.  (See his comment
on the SerDes doc:  https://cwiki.apache.org/confluence/display/Hive/SerDe?focusedCommentId=39620650#comment-39620650.)
 So I'm taking them out.

> In HIVE-5263 we started serializing OI's when cloning the plan. This was a great boost
in speed for many queries. In the future we'd like to stop copying the OI's, perhaps in HIVE-4396.
> Until then Custom Serdes will not work on trunk. This is a fix to allow custom serdes
such as the Hive JSon Serde work until we address the fact we don't want to have to copy the
OI's. Since this is modifying the byte code, we should recommend that the no-arg constructor
be added.
