Subject [jira] [Commented] (HIVE-3163) enhance Deserialize to add a method to show whether the column names are derived from the Deserializer
Date Wed, 20 Jun 2012 04:12:43 GMT

    [ https://issues.apache.org/jira/browse/HIVE-3163?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13397245#comment-13397245
] 

Edward Capriolo commented on HIVE-3163:
---------------------------------------

You know I am not sure exactly why/when this is true. I have a serde not hard coded in serde-utils
that does not require columns to be defined. But yes we should get rid of the hard codes.
(the class mentions something about lazy-loading as well in the comments)

> There are some serdes: ThriftDeserializer and AvroDeserilizer which 
> contain the column information. I mean, the user does not need to specify the
> column schema.
> Currently, this information is hard-coded. SerDeUtils has a method to get this
> information from the name of the serde.
> Ideally, Deserializer should be extended to add this method.
