> Seek behavior difference between NativeS3FsInputStream and DFSInputStream

> Key: HADOOP-11270
> URL: https://issues.apache.org/jira/browse/HADOOP-11270
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/s3
> Affects Versions: 2.5.1
> Reporter: Venkata Puneet Ravuri

> 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:-
