Research direction

Start with the dr_elephant.log stack trace and inspect SparkFetcher and ApplicationAttemptInfo, where the reported lastUpdated field is rejected. Compare the expected application status data for Spark 2.1 with the fields handled there, and verify that Spark jobs load without the reported exception.
