Thomas Graves commented on SPARK-18085:
---------------------------------------

Perhaps we can clarify the title on this jira to be something like history

> It's a known fact that the History Server currently has some annoying issues 
> when serving lots of applications, and when serving large applications.
> I'm filing this umbrella to track work related to addressing those issues. 
> I'll be attaching a document shortly describing the issues and suggesting a 
> path to how to solve them.
