>                 Key: SPARK-24200
>                 URL: https://issues.apache.org/jira/browse/SPARK-24200
>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 2.3.0
>            Reporter: kumar
>            Priority: Major

> String folder = "/Users/test/data/* /* ";
> sparkContext.textFile(folder, 1).toJavaRDD() 
> Is asterisks mandatory to read a folder -Yes, otherwise it does not read files under subdirectories.
> What if I get a folder which is having more subdirectories than the number of asterisks mentioned ? 
> For example:
> 1) {{/Users/test/data/}} This would work ONLY if I get data as /Users/test/data/folder1/file.txt
> 2)How to make this expression as *generic* ? It should still work if I get a folder as: {{/Users/test/data/folder1/folder2/folder3/folder4}}
> My input folder structure is not same all the time.
> Is there anything exists in Spark to handle this kind of scenario ? I know you might have thought about this, but i am wondering why this has not been implemented ?
