Arun C Murthy reassigned MAPREDUCE-4568: ---------------------------------------- Assignee: Arun C Murthy > 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 > Assignee: Arun C Murthy > > 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). -- This message is automatically generated by JIRA.
