Ravi Prakash updated HDFS-3794:
-------------------------------
Attachment: HDFS-3794.patch
Attaching a patch that fixes the issue. Its too trivial to write a unit test
(which will have to be pretty complicated :'( ... I tried briefly)
Here's the testing I did
1. Small file with offset. Worked
2. Big file (multiple blocks) with offset. Worked
3. Big file with offset greater than file size. Correctly threw a
RemoteException
> WebHDFS Open used with Offset returns the original (and incorrect) Content
> Length in the HTTP Header.

> Components: webhdfs

> When an offset is specified, the HTTP header Content Length still contains
> the original file size. e.g. if the original file is 100 bytes, and the
> offset specified it 10, then HTTP Content Length ought to be 90. Currently it
> is still returned as 100.
> This causes curl to give error 18, and JAVA to throw ConnectionClosedException
