Subject [jira] Updated: (HADOOP-1449) Example for contrib/data_join
Date Tue, 12 Jun 2007 23:19:26 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-1449?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Owen O'Malley updated HADOOP-1449:

    Assignee: Senthil Subramanian
      Status: Open  (was: Patch Available)

This patch has some issues:
  1. New code should not have @author tags (and we will remove them from old code).
  2. There are a couple methods bodies that do the default action. In particular,
    a. constructors for SampleTaggedMapOutput that call "super()".
    b. SampleDataJoinMapper configure and close just call the super method.
    c. SampleDataJoinReducer configure and close just call the super method.

> DataJoin under "contrib/data_join/src/java/org/apache/hadoop/contrib/utils/join" is useful
but is missing examples. I plan to add a simple example which can demonstrate a INNER JOIN
between two text files based on the values on a column using this framework.
