possible double setting of java.library.path introduced by HADOOP-838
---------------------------------------------------------------------

                 Key: HADOOP-1493
                 URL: https://issues.apache.org/jira/browse/HADOOP-1493
             Project: Hadoop
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.14.0
            Reporter: Enis Soztutar
            Assignee: Enis Soztutar
             Fix For: 0.14.0


HADOOP-838 introduced setting java.library.path to run the {{TaskTracker$Child}} from the
TaskTracker's library.path, so that the native lib path is passed to the child. However if
we also want to set -Djava.library.path from the configuration by "mapred.child.java.opts",
than the child java process is called with two -Djava.library.path properties, and java seems
to ignore the former, rather than use the two. This situation prevents using -Djava.library.path
in "mapred.child.java.opts".
