Akira Ajisaka updated MAPREDUCE-5490: ------------------------------------- Resolution: Won't Fix Status: Resolved (was: Patch Available) branch-1 is EoL. Closing this. > MapReduce doesn't set the environment variable for children processes > --------------------------------------------------------------------- > > Key: MAPREDUCE-5490 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-5490 > Project: Hadoop Map/Reduce > Issue Type: Bug > Affects Versions: 1.2.1 > Reporter: Owen O'Malley > Assignee: Owen O'Malley > Priority: Major > Labels: BB2015-05-TBR > Attachments: MAPREDUCE-5490.patch, mr-5490.patch, mr-5490.patch > > > Currently, MapReduce uses the command line argument to pass the classpath to > the child. This breaks if the process forks a child that needs the same > classpath. Such a case happens in Hive when it uses map-side joins. I propose > that we make MapReduce in branch-1 use the CLASSPATH environment variable > like YARN does. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
