Michael Mior 1437e344ec [SPARK-22050][CORE] Allow BlockUpdated events to be optionally logged to the event log ... ## What changes were proposed in this pull request? I see that block updates are not logged to the event log. This makes sense as a default for performance reasons. However, I find it helpful when trying to get a better understanding of caching for a job to be able to log these updates. This PR adds a configuration setting `spark.eventLog.blockUpdates` (defaulting to false) which allows block updates to be recorded in the log. This contribution is original work which is licensed to the Apache Spark project. ## How was this patch tested? Current and additional unit tests.
