Subject [jira] [Comment Edited] (SPARK-21996) Streaming ignores files with spaces in the file names

-------------------------------------------------------------

I can reproduce this issue for master branch, and found out it was from using {{.toString}}
instead of {{.getPath}} to get the file path in string format. 

I pushed a PR to make it work for streaming. But there're other places in spark where we're
using `.toString`. Not sure if it's a general concern.

>    Affects Versions: 2.2.0
>         Environment: openjdk version "1.8.0_131"
> OpenJDK Runtime Environment (build 1.8.0_131-8u131-b11-2ubuntu1.17.04.3-b11)

> I tried to stream text files from folder and noticed that files inside this folder with
spaces in their names ignored and there are some warnings in the log:
> {code}
> 17/09/13 16:15:14 WARN InMemoryFileIndex: The directory file:/in/two%20two.txt was not
found. Was it deleted very recently?
> {code}
> I found that this happens due to duplicate file path URI encoding (I suppose) and the
actual URI inside path objects looks like this {{file:/in/two%2520two.txt}}.
> To reproduce this issue just place some text files with spaces in their names and execute
some simple streaming code:
> {code:java}
> /in
>     /one.txt
>     /two two.txt
>     /three.txt
> {code}
> {code}
> sparkSession.readStream.textFile("/in")
>       .writeStream
>       .option("checkpointLocation", "/checkpoint")
>       .format("text")
>       .start("/out")
>       .awaitTermination()
> {code}
> The result will contain only content of files {{one.txt}} and {{three.txt}}.
