Major Description
Trying to load the web UI Executors page when using dynamic allocation running on yarn can lead to an IndexOutOfBoundsException Exception.
I'm assuming the number of executors is changing as its trying to be loaded which is causing this as during this time it was letting executors go.
HTTP ERROR 500
Problem accessing /executors/. Reason:
Server Error

Simply reloading eventually gets the ui to come up so its not a blocker but not a very friendly experience either.
