Attachment: MAPREDUCE-4458.patch

> 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.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.
