Allen Wittenauer commented on MAPREDUCE-6491: --------------------------------------------- a) DYLD_LIBRARY_PATH should be in the list b) As mentioned several times, this won't work if a job (e.g., streaming) calls the shell scripts with the default values. > Environment variable handling assumes values should be appended > --------------------------------------------------------------- > > Key: MAPREDUCE-6491 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-6491 > Project: Hadoop Map/Reduce > Issue Type: Bug > Affects Versions: 2.2.0 > Reporter: Jason Lowe > Assignee: Dustin Cote > Attachments: MAPREDUCE-6491.011.patch, YARN-2369-10.patch, > YARN-2369-1.patch, YARN-2369-2.patch, YARN-2369-3.patch, YARN-2369-4.patch, > YARN-2369-5.patch, YARN-2369-6.patch, YARN-2369-7.patch, YARN-2369-8.patch, > YARN-2369-9.patch > > > When processing environment variables for a container context the code > assumes that the value should be appended to any pre-existing value in the > environment. This may be desired behavior for handling path-like environment > variables such as PATH, LD_LIBRARY_PATH, CLASSPATH, etc. but it is a > non-intuitive and harmful way to handle any variable that does not have > path-like semantics. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
