[ http://issues.apache.org/jira/browse/HADOOP-366?page=comments#action_12430995 ] Jean-Baptiste Quenot commented on HADOOP-366: ---------------------------------------------
In fact Owen's point is to say that you can put jars in the jar. Is there any reason for this "hack" to unpack mapred.jar in TaskRunner and look for a "lib" directory containing jars? Isn't that too much of magic? Would it be a viable option to allow MapReduce tasks to take a list of jars instead? Or is there a compelling reason to only give a single Jar? > Should be able to specify more than one jar into a JobConf file > --------------------------------------------------------------- > > Key: HADOOP-366 > URL: http://issues.apache.org/jira/browse/HADOOP-366 > Project: Hadoop > Issue Type: Improvement > Components: mapred > Affects Versions: 0.4.0 > Reporter: Thomas FRIOL > > 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.
