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.
> No application number limit in spark history server
> ---------------------------------------------------
>
> Key: SPARK-6108
> URL: https://issues.apache.org/jira/browse/SPARK-6108
> Project: Spark
> Issue Type: Improvement
> Components: Web UI
> Affects Versions: 1.2.1
> Reporter: Xia Hu
> Priority: Minor
>
> 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.
