Amar Kamat commented on HADOOP-2838:
------------------------------------
bq. Stumbled on this patch.. what happens if the value of mapred.child.env does
not have a well formed string - like doesn't have "key=value" but only key ?
Has this been taken care of ?
TaskRunner will fail in child launch leading to task failure ultimately leading
to job failure. I see it as something similar to bad mapred code.
> 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.
