> There is a difference in behavior while seeking a given file present
> in S3 using NativeS3FileSystem$NativeS3FsInputStream and a file present in
> HDFS using DFSInputStream.
> If we seek to the end of the file incase of NativeS3FsInputStream, it fails
> with exception "java.io.EOFException: Attempted to seek or read past the end
> of the file". That is because a getObject request is issued on the S3 object
> with range start as value of length of file.
> This is the complete exception stack:-

> the file
