> Allow ApplicationHistoryProviders to provide their own text when there aren't 
> any complete apps
> -----------------------------------------------------------------------------------------------
>                 Key: SPARK-10541
>                 URL: https://issues.apache.org/jira/browse/SPARK-10541
>             Project: Spark
>          Issue Type: Improvement
>          Components: Web UI
>    Affects Versions: 1.5.0
>            Reporter: Steve Loughran
>            Assignee: Apache Spark
>            Priority: Minor
> The current History Server text when there are no complete apps is hard coded 
> for the FS provider and talks about log directories. As it is static text, it 
> doesn't get any recent information from that FS provider itself, such as the 
> directory it is looking at.
> For other ApplicationHistoryProviders, there will be different reasons
> for the list being empty, including, in the timeline implementation: failure 
> to talk to the server, authentication failure, or simply no events being 
> present.
> Even {{FsHistoryProvider}} could help users by actually printing what the log 
> directory was.
> If a method {{emptyListingText()}} `was supported, each implementation could 
> provide a live explanation of the current state
