[jira] Created: (HADOOP-6453) Hadoop wrapper script shouldn't ignore an existing JAVA_LIBRARY_PATH

Hadoop wrapper script shouldn't ignore an existing JAVA_LIBRARY_PATH
--------------------------------------------------------------------

                 Key: HADOOP-6453
                 URL: https://issues.apache.org/jira/browse/HADOOP-6453
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 0.20.1
            Reporter: Chad Metcalf
            Priority: Minor
             Fix For: 0.20.2


Currently the hadoop wrapper script assumes its the only place that uses JAVA_LIBRARY_PATH and initializes it to a blank line.

JAVA_LIBRARY_PATH=''

This prevents anyone from setting this outside of the hadoop wrapper (say hadoop-config.sh) for their own native libraries.

The fix is pretty simple. Don't initialize it to '' and append the native libs like normal.
