Xuefu Zhang commented on HIVE-11250:
------------------------------------
In addition to the problem, I think changing value of hive.execution.engine
from spark to others (say, mr) should result in destroying the spark session.
While this is probably not comment in a production environment, I ran into
problem in testing that I switched to MR and found that the MR job doesn't make
any progress because all containers are currently held by the spark session.
> Change in spark.executor.instances (and others) doesn't take effect after RSC
> is launched for HS2 [Spark Brnach]
