Review Comment:
   Yes I've seen that, but it wasn't overridden. Even if I explicitly added   
   
   ```xml
   <property>
       <name>hadoop.http.cross-origin.allowed-headers</name>
       <value>X-Requested-With,Content-Type,Accept,Origin</value>
     </property>
   ```
   
   to core-site.xml, it was not picked up for some reason.

> This causes knox to urlencode the request body so that uploading a CVS file 
> 1,2,3 will result 1%2C2%2C3.
> Instead of application/x-www-form-urlencoded I think the encoding should be 
> set to application/octet-stream.
