GitHub user zsxwing opened a pull request:
https://github.com/apache/spark/pull/11615
Add spark.ui.threads to set the max number of the UI threads
## What changes were proposed in this pull request?
As each acceptor in Jetty will use one thread, the number of threads should
at least be the number of acceptors plus 1. Otherwise, the thread pool of Jetty
server may be exhausted by acceptors and not be able to response any request.
## How was this patch tested?
Just make sure we don't break any existing tests
