Steve Loughran commented on SPARK-19715:
----------------------------------------
This is a silly question, but has the situation " a filesystem schema has
changed" ever arisen? Because I can see the risk of that being lower than the
risk that a file with the same name is added to > 1 directory included in the
same scan
> Option to Strip Paths in FileSource

> Key: SPARK-19715
> URL: https://issues.apache.org/jira/browse/SPARK-19715
> Project: Spark
> Issue Type: New Feature
> Components: Structured Streaming
> Affects Versions: 2.1.0
> Reporter: Michael Armbrust
>
> Today, we compare the whole path when deciding if a file is new in the
> FileSource for structured streaming. However, this cause cause false
> negatives in the case where the path has changed in a cosmetic way (i.e.
> changing s3n to s3a). We should add an option {{fileNameOnly}} that causes
> the new file check to be based only on the filename (but still store the
> whole path in the log).
