## What changes were proposed in this pull request?
The current code is very verbose on shutdown.
The changes I propose is to change the log level when the driver is shutting down and the RPC connections are closed (RpcEnvStoppedException).
## How was this patch tested?
Tested with word count(deploy-mode = cluster, master = yarn, num-executors = 4) with 300GB of data.

logInfo, not debug, probably. I can see reducing the level if you know your'e stopping, but not in other cases. The code style here would have to be fixed. For example you don't use string interpolation here.

[GitHub] spark issue #18547: [SPARK-21321][Spark Core] Spark very verbose on shutdown
Posted by tgravescs <gi...@git.apache.org>.
Github user tgravescs commented on the issue:
https://github.com/apache/spark/pull/18547
There is no reason to print out messages that aren't useful to the users. Many users see Warnings and read them and think there is a problem with their application or configuration. Most of these are really for advanced users or devs trying to debug what is going on. So changing them to debug makes sense to me.
There are also times that shutdown can take a very long time and all its doing it spewing these log messages. For instance when you have a backlog of events in the event queue. I have seen multiple minutes of it just throwing the warnings like: Message $message dropped. ${e.getMessage}
dynamic allocation can also add a lot of warning messages that are unneeded. When I'm shutting down things should stop quickly and release the resources for others to use.
I still need to review in detail but these should just be in the shutdown case, other times I agree that you may want to see these.
We should definitely update the description here and in the jira to have more details though.
