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.
