[jira] [Created] (MAPREDUCE-4568) Throw "early" exception when
duplicate files or archives are found in distributed cache
Mohammad Kamrul Islam created MAPREDUCE-4568:
------------------------------------------------
Summary: Throw "early" exception when duplicate files or archives are found in distributed cache
Key: MAPREDUCE-4568
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4568
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Mohammad Kamrul Islam
According to #MAPREDUCE-4549, Hadoop 2.x throws exception if duplicates found in cacheFiles or cacheArchives. The exception throws during job submission.
This JIRA is to throw the exception ==early== when it is first added to the Distributed Cache through addCacheFile or addFileToClassPath.
It will help the client to decide whether to fail-fast or continue w/o the duplicated entries.
Alternatively, Hadoop could provide a knob where user will choose whether to throw error( coming behavior) or silently ignore (old behavior).
