                 Key: HDFS-9335

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
