> Spark application event logs are not very NameNode-friendly
> -----------------------------------------------------------
>
>                 Key: SPARK-2261
>                 URL: https://issues.apache.org/jira/browse/SPARK-2261
>             Project: Spark
>          Issue Type: Improvement
>          Components: Spark Core
>    Affects Versions: 1.0.0
>            Reporter: Marcelo Vanzin
>            Priority: Minor
>
> Currently, EventLoggingListener will generate application logs using, in the worst case, five different entries in the file system:
> * The directory to hold the files
> * One file for the Spark version
> * One file for the event logs
> * One file to identify the compression codec of the event logs
> * One file to say the application is finished.
> It would be better to be more friendly to the NameNodes and use a single entry for all of those.
