>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: hdfs client
>    Affects Versions: 0.23.1
>            Reporter: Zhanwei.Wang

> STEP:
> 1, create a new EMPTY file
> 2, read it using webhdfs.
> RESULT:
> expected: get a empty file
> I got: 
> {"RemoteException":{"exception":"IOException","javaClassName":"java.io.IOException","message":"Offset=0
>  out of the range [0, 0); OPEN, path=/testFile"}}
> First of all, [0, 0) is not a valid range, and I think read a empty file 
> should be OK.
