 Provide Spark the location of the SparkRDMA plugin jars by using the extraClassPath option.  For standalone mode this can
 be added to either spark-defaults.conf or any runtime configuration file.  For client mode this **must** be added to spark-defaults.conf. For Spark 2.0.0 (Replace with 2.1.0, 2.2.0 or 2.3.0 according to your Spark version):
 ```
-spark.driver.extraClassPath   /path/to/SparkRDMA/target/spark-rdma-2.0-for-spark-2.0.0-jar-with-dependencies.jar
-spark.executor.extraClassPath /path/to/SparkRDMA/target/spark-rdma-2.0-for-spark-2.0.0-jar-with-dependencies.jar
