> 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
> Assignee: Marcelo Vanzin
> Priority: Minor
> Fix For: 1.3.0
>
>
> 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.
