Spark 0.9.0 does include standalone scheduler HA, but it requires running multiple masters. The docs are located here: https://spark.apache.org/docs/0.9.0/spark-standalone.html#high-availability
0.9.0 also includes driver HA (for long-running normal or streaming jobs), allowing you to submit a driver into the standalone cluster which will be restarted automatically if it crashes. That doc is on the same page: https://spark.apache.org/docs/0.9.0/spark-standalone.html#launching-applications-inside-the-cluster Please let me know if you have further questions.
