Jinghui Wang updated MAPREDUCE-5490: ------------------------------------ Attachment: (was: MAPREDUCE-5490.patch) > 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 > 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 (v6.1.5#6160)
