Subject [jira] [Resolved] (HADOOP-1277) The class generated by Hadoop Record rcc should provide a static method to return the DDL string
Date Sat, 16 Jul 2011 19:38:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-1277?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Harsh J resolved HADOOP-1277.
-----------------------------

    Resolution: Won't Fix

Resolving as Won't Fix, since the whole recordio component is now deprecated in favor of Avro
(and technically ought to be removed in 0.22/0.23).

Please see https://issues.apache.org/jira/browse/HADOOP-6155

>             Project: Hadoop Common
>          Issue Type: New Feature
>          Components: record

> The method will look like:
> public static string getDDL();
> With this class, when a map/reduce job write out sequence file swith such a generated
class as its value class, the job
> can also save the DDL of the class into a file.
> With such a file around, we can implement a record reader that can generate the required
class on demand, thus, can read 
> a sequence file of Hadoop Records without having the class a priori.
