Description
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.
