**BEFORE**
```

scala> spark.sharedState
res0: org.apache.spark.sql.internal.SharedState = org.apache.spark.sql.internal.SharedState5793cd84
scala> new java.net.URL("file:///tmp/1.txt").openConnection.getInputStream
res1: java.io.InputStream = org.apache.hadoop.fs.ChecksumFileSystem$FSDataBoundedInputStream22846025
scala> import org.apache.hadoop.fs._
import org.apache.hadoop.fs._
scala> FileSystem.get(new Path("file:///tmp/1.txt").toUri, spark.sparkContext.hadoopConfiguration)
res2: org.apache.hadoop.fs.FileSystem = org.apache.hadoop.fs.LocalFileSystem5a930c03
```
**AFTER**
```
➜ spark git:(SPARK-31692) ✗ ./bin/spark-shell --conf spark.hadoop.fs.file.impl=org.apache.hadoop.fs.RawLocalFileSystem
scala> spark.sharedState
res0: org.apache.spark.sql.internal.SharedState = org.apache.spark.sql.internal.SharedState5c24a636

scala> import org.apache.hadoop.fs._
import org.apache.hadoop.fs._
scala> FileSystem.get(new Path("file:///tmp/1.txt").toUri, spark.sparkContext.hadoopConfiguration)
res2: org.apache.hadoop.fs.FileSystem = LocalFS
scala> FileSystem.get(new Path("file:///tmp/1.txt").toUri, spark.sparkContext.hadoopConfiguration).getClass
res3: Class[_ <: org.apache.hadoop.fs.FileSystem] = class org.apache.hadoop.fs.RawLocalFileSystem
```
The type of FileSystem object created(you can check the last statement in the above snippets) in the above two cases are different, which should not have been the case
No
Tested locally.
Added Unit test
