Hi Community, In Spark 2.0.0 we upgrade to use jersey2 ( https://issues.apache.org/jira/browse/SPARK-12154) instead of jersey 1.9, while for the whole Hadoop we still stick on the old version. This will bring in some issues when yarn timeline service is enabled ( https://issues.apache.org/jira/browse/SPARK-15343). For any Spark2 application running on yarn with timeline service enabled will be failed.
Just a heads up if you happened to run into this issue you could disable yarn timeline service through configuration "spark.hadoop.yarn.timeline-service.enabled = false" to disable spark on yarn to use this feature. Also we will fix this in the yarn side. Thanks Saisai
