> HistoryServerDiskManager will fail on appStoreDir in s3
> -------------------------------------------------------

> Key: SPARK-30190
> URL: https://issues.apache.org/jira/browse/SPARK-30190
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 3.0.0
> Reporter: thierry accart
> Priority: Major

> Hi
> While setting spark.eventLog.dir to s3a://... I realized that it *requires destination directory to preexists for S3*
> This is explained I think in HistoryServerDiskManager's appStoreDir: it tries check if directory exists or can be created
> {{if (!appStoreDir.isDirectory() && !appStoreDir.mkdir()) \{throw new IllegalArgumentException(s"Failed to create app directory ($appStoreDir).")}}}
> But in S3, a directory does not exists and cannot be created: directories don't exists by themselves, they are only materialized due to existence of objects.
> Before proposing a patch, I wanted to know what are the prefered options :
> should we have a spark option to skip the appStoreDir test, or skip it only when a particular scheme is set, have a custom implementation of HistoryServerDiskManager ...?
>
> _Note for people facing the {{IllegalArgumentException:}} {{Failed to create app directory}} *you just have to put an empty file in bucket destination 'path'*._
