[jira] [Commented] (SPARK-6108) No application number limit in spark history server

    [ https://issues.apache.org/jira/browse/SPARK-6108?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14941125#comment-14941125 ] 

Steve Loughran commented on SPARK-6108:
---------------------------------------

If this is an issue, then having a time window is probably better than number of files —though care would be needed to avoid deleting histories of running applications

> 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.
