Make sure you set the CMS GC on both the driver (using `--driver-java-options` in `spark-submit`) and the executors (using [Spark configuration](configuration.html#runtime-environment) `spark.executor.extraJavaOptions`). * **Other tips**: To further reduce GC overheads, here are some more tips to try. - - Use Tachyon for off-heap storage of persisted RDDs. See more detail in the [Spark Programming Guide](programming-guide.html#rdd-persistence). + - Persist RDDs using the `OFF_HEAP` storage level. See more detail in the [Spark Programming Guide](programming-guide.html#rdd-persistence). - Use more executors with smaller heap sizes. This will reduce the GC pressure within each JVM heap. |
