+HADOOP_GREMLIN_LIBS and Spark
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The TinkerPop reference documentation has always mentioned that the `gremlin-spark` `/lib`
directory needed to be
+added to `HADOOP_GREMLIN_LIBS` environment variable. In reality, that was not truly necessary.
With Spark 1.x having
+`gremlin-spark` in `HADOOP_GREMLIN_LIBS` hasn't been a problem, but Spark 2.0 introduces
a check for duplicate jars
+on the path which will cause job initialization to fail. As a result, going forward with
TinkerPop 3.3.0, the
+`gremlin-spark` `lib` directory should not be included in `HADOOP_GREMLIN_LIBS`.
+
 Deprecation Removal
 ^^^^^^^^^^^^^^^^^^^
