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".
