[jira] Created: (HADOOP-838) TaskRunner.run() doesn't pass along
the 'java.library.path' to the child (task) jvm
TaskRunner.run() doesn't pass along the 'java.library.path' to the child (task) jvm
-----------------------------------------------------------------------------------
Key: HADOOP-838
URL: http://issues.apache.org/jira/browse/HADOOP-838
Project: Hadoop
Issue Type: Bug
Components: mapred
Affects Versions: 0.9.2
Reporter: Arun C Murthy
Assigned To: Arun C Murthy
Since TaskRunner.run doesn't pass along java.library.path of the parent (TT) to the child (task) the native library path (if needed) is missing and hence it cannot load the native library. The fix is to do a System.getProperty and add it to the child jvm's arguments.

------------------------------------
+1
With LD_LIBRARY_PATH set to *not* include the hadoop native library, I successfully ran all the unit tests and saw that the native library was always loaded.
