Subject [jira] Updated: (HADOOP-2838) Add HADOOP_LIBRARY_PATH config setting so Hadoop will include external directories for jni
Date Wed, 10 Jun 2009 06:21:07 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-2838?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Amar Kamat updated HADOOP-2838:
-------------------------------

    Release Note: 
Now the users can set environment variables using mapred.child.env. They can do the following

X=Y : set X to Y
X=$X:Y : Append Y to X (which should be taken from the tasktracker)

> Add HADOOP_LIBRARY_PATH config setting so Hadoop will include external directories for
jni

> Currently there is no way to configure Hadoop to use external JNI directories. I propose
we add a new variable like HADOOP_CLASS_PATH that is added to the JAVA_LIBRARY_PATH before
the process is run.
