We should throw a 400 with the appropriate message. When an invalid value is
sent, we return the following content
{code}
"RemoteException":{"className":"com.sun.jersey.api.ParamException$QueryParamException","message":"java.lang.NumberFormatException:
For input string: \"invalid\""}}
{code}
> webhdfs open a file and send 0 or invalid bufferSize throws a 500 with xml
