agate commented on SPARK-15544:
-------------------------------
Can we please increase the priority of this bug since it exists in latest Spark
2.3.0 too? We have observed this during upgrade scenario (with Spark 1.6.3),
where we have to shutdown zookeeper, which has the adverse side-effect of spark
master shutting down on other nodes which is not very ideal.
