Subject [jira] [Updated] (HIVE-5380) Non-default OI constructors should be supported for backwards compatibility
Date Fri, 07 Feb 2014 21:55:19 GMT

     [ https://issues.apache.org/jira/browse/HIVE-5380?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Brock Noland updated HIVE-5380:
-------------------------------

    Description: 
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.
