Jonathan Eagles commented on MAPREDUCE-4458: -------------------------------------------- Rob, can you update this patch? It fails to apply. > Warn if java.library.path is used for AM or Task > ------------------------------------------------ > > Key: MAPREDUCE-4458 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4458 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: mrv2 > Affects Versions: 0.23.3, 3.0.0, 2.0.2-alpha > Reporter: Robert Joseph Evans > Assignee: Robert Parker > Attachments: MAPREDUCE-4458-2.patch, MAPREDUCE-4458.patch > > > If java.library.path is used on the command line for launching an MRAppMaster > or an MR Task, it could conflict with how standard Hadoop/HDFS JNI libraries > and dependencies are found. At a minimum the client should output a warning > and ask the user to switch to LD_LIBRARY_PATH. It would be nice to > automatically do this for them but parsing the command line is scary so just > a warning is probably good enough for now. -- This message is automatically generated by JIRA.
