Subject [jira] Updated: (HADOOP-1277) The class generated by Hadoop Record rcc should provide a static method to return the DDL string
Date Wed, 27 Jun 2007 17:17:26 GMT

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

Sameer Paranjpye updated HADOOP-1277:
-------------------------------------

    Component/s: record

> The class generated by Hadoop Record rcc should provide a static method to return the
DDL string
> ------------------------------------------------------------------------------------------------
>
>                 Key: HADOOP-1277
>                 URL: https://issues.apache.org/jira/browse/HADOOP-1277
>             Project: Hadoop
>          Issue Type: New Feature
>          Components: record
>            Reporter: Runping Qi
>
> 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.
