Subject [jira] [Commented] (MAPREDUCE-3390) NPE while submitting job
Date Thu, 10 Nov 2011 19:44:51 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3390?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13147960#comment-13147960
] 

Alejandro Abdelnur commented on MAPREDUCE-3390:
-----------------------------------------------

There is something wrong in how things works here, the generated-classpath is useless as its
obtained from the build environment where Hadoop was built, see MAPREDUCE-3389. Thus makes
it unusable by downstream projects.
