Devaraj K commented on MAPREDUCE-2297:
--------------------------------------
Hi Todd, I agree with you for job specific configuration. If we configure
archives (contains invalid path) common for all jobs then all jobs will fail.
Here all jobs may not depend on all the archives.
Consider the case of Hive, if we configure any invalid path for the property
"hive.aux.jars.path" all the jobs will fail which is not using that jar also.
> All map reduce tasks are failing if we give invalid path jar file for Job

> This can be reproduced by giving the invalid jar file for the Job or it can

> <description>Provided for adding auxillaryjarsPath</description>
> </property>
> 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.
