Subject [jira] Updated: (HIVE-1015) Java MapReduce wrapper for TRANSFORM/MAP/REDUCE scripts
Date Wed, 06 Jan 2010 16:39:54 GMT

     [ https://issues.apache.org/jira/browse/HIVE-1015?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Larry Ogrodnek updated HIVE-1015:

    Attachment: HIVE-1015.patch

Here's a new patch with a .q file using an example mapper and reducer.

I also removed the dependency of these classes on apache commons lang, since there was only
a single use of StringUtils.join(), and it's one less thing to specify on the classpath in
the USING clause....

> Larry Ogrodnek has written a set of wrapper classes that make it possible
> to write Hive TRANSFORM/MAP/REDUCE scripts in Java in a style that
> more closely resembles conventional Hadoop MR programs.
> A blog post describing this library can be found here: http://dev.bizo.com/2009/10/hive-map-reduce-in-java.html
> The source code (with Apache license) is available here: http://github.com/ogrodnek/shmrj
> We should add this to contrib.
