Marcelo Vanzin resolved SPARK-6108.
-----------------------------------
    Resolution: Won't Fix

There are many ways currently to control how many applications are kept around; the SHS can even clean up old logs.

HDFS overhead is less of a problem since we started using a single file for event logs.

>          Issue Type: Improvement
>          Components: Web UI
>    Affects Versions: 1.2.1

> There isn't a limit for the application number in spark history server. The only limit I found is "spark.history.retainedApplications", but this one only controls how many apps could be stored in memory. 
> But I think a history application number limit is needed, for if it's number is too big, it can be inconvenient for both HDFS and history server.
