 * `JAVA_HOME`, the location where Java is installed (if it's not on your default `PATH`)
 * `PYSPARK_PYTHON`, the Python binary to use for PySpark
 * `SPARK_LOCAL_IP`, to configure which IP address of the machine to bind to.
-* `SPARK_LIBRARY_PATH`, to add search directories for native libraries.
 * `SPARK_CLASSPATH`, to add elements to Spark's classpath that you want to be present for _all_ applications.
    Note that applications can also add dependencies for themselves through `SparkContext.addJar` -- we recommend
    doing that when possible.
