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.
