[jira] [Commented] (SPARK-18273) DataFrameReader.load takes a lot
of time to start the job if a lot of file/dir paths are pass

------------------------------------------
Thanks [~srowen]. Didn't realize that I could actually pass glob pattern. Thank you so much.

> Affects Versions: 2.0.1
> Reporter: Aniket Bhatnagar
> Priority: Minor
>
> If the paths Seq parameter contains a lot of elements, then DataFrameReader.load takes a lot of time starting the job as it attempts to check if each of the path exists using fs.exists. There should be a boolean configuration option to disable the checking for path's existence and that should be passed in as parameter to DataSource.resolveRelation call.
