> a.  Submit HTTP POST request using the URL in the Location header with the file data to be appended
> {code}
> curl -i -X POST -T /opt/folder/file  "http://host-10-19-92-117:50075/webhdfs/v1/folder1/file1?op=APPEND&namenoderpcaddress=hacluster&buffersize=1"
> {code}
> b. The client receives a response with zero content length
> c. Now execute the same for a folder (/opt/folder) rather than Local file  
> {code}
> curl -i -X POST -T /opt/folder  "http://host-10-19-92-117:50075/webhdfs/v1/folder1/file1?op=APPEND&namenoderpcaddress=hacluster&buffersize=1"
> {code}
> d. No response will be given to the user and it will hang
