Hi , Hadoop 2.x is going to fail the job submission if there are duplicated entries (with same name) found in the distributed cache. In earlier version , it was silently ignore the second entry.
I created a JIRA (https://issues.apache.org/jira/browse/MAPREDUCE-4568) regarding this. Based on this , we might need to change our code. If possible, please add your comments in the JIRA. Regards, Mohammad
