Subject [jira] [Commented] (MAPREDUCE-2297) All map reduce tasks are failing if we give invalid path jar file for Job
Date Tue, 24 May 2011 13:41:54 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2297?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13038554#comment-13038554
] 

Devaraj K commented on MAPREDUCE-2297:
--------------------------------------

As the exception stack trace says, I meant in the title all map reduce jobs are failing. 


"hive.aux.jars.path" is system level config for hive. Hive uses these jars for all the jobs
it submits. I think there is no provision of submitting jars for specific query.

from hive.

> If we configure an invalid path for jar file, It is making all map reduce tasks to fail
even those jobs are not depending on this jar file and it is giving the below exception.
