Subject [jira] [Commented] (MAPREDUCE-4068) Jars in lib subdirectory of the submittable JAR are not added to the classpath
Date Thu, 02 Aug 2012 03:56:03 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4068?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13427096#comment-13427096

Radim Kolar commented on MAPREDUCE-4068:

I do not see it either. Its major problem while migrating from mrv1. Libs in lib/ are used
only in hadoop driver during job submission, but not in map/reduce YarnChild.java

>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: mrv2
>    Affects Versions: 0.23.1
>            Reporter: Ahmed Radwan
>             Fix For: 0.23.2
> Prior to hadoop 0.23, users could add third party jars to the lib subdirectory of the
submitted job jar and they become available in the task's classpath. I see this functionality
was in TaskRunner.java, but I can't see similar functionality in hadoop 0.23 (neither in MapReduceChildJVM.java
nor other places).
