Haohui Mai commented on HDFS-8621:
----------------------------------

DT related calls are only for security purposes thus it should not be supported 
by the WebImageViewer.

> Implement GETDELEGATIONTOKEN and GETDELEGATIONTOKENS operation for 
> WebImageViewer

> In Hadoop 2.7.0, WebImageViewer supports the following operations:
> {code}
>    .GETFILESTATUS
>    .LISTSTATUS
>    .GETACLSTATUS
> {code}
> I'm thinking it would be better for administrators if  {code} 
> .GETDELEGATIONTOKEN  {code}  and  {code} .GETDELEGATIONTOKENS  {code}  are 
> supported.
