Subject [jira] Commented: (HADOOP-366) Should be able to specify more than one jar into a JobConf file
Date Wed, 30 Aug 2006 16:32:24 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-366?page=comments#action_12431619 ] 
            
Jean-Baptiste Quenot commented on HADOOP-366:
---------------------------------------------

I hear you.  But "lib" at the root is not standard WAR, is it?

The structure is:

{code}
WEB-INF/
  |
  \__ classes
  |
  \__ lib
  |  |
  |  \__ lib1.jar
  |  |
  |  \__ lib2.jar
  |
  \__ web.xml
{code}

And in web.xml we could define a webapp listener that would be invoked upon webapp startup.

> A job should be able to specify more than one jar file into its JobConf file because
sometimes custom Map and Reduce classes or just InputFormat classes uses objects coming from
other jar files. For now, we have to build a unique jar to make Hadoop mapreduce operations
works.
