Wei-Chiu Chuang commented on HDFS-12950:

Thank you, Brahma.

I posted a patch to make WebImageViewer throw Runtime exception when it detects 
the secure mode is enabled in configuration. Also updated doc and command line 
help to indicate this use case is not supported.

> if we execute ls, it will throw following.
> {noformat}
> hdfs dfs -ls webhdfs://
> ls: Invalid value for webhdfs parameter "op"
> {noformat}
> When client is configured with security (i.e "hadoop.security.authentication= 
> then webhdfs will request getdelegation token which is not implemented and 
> hence it will  throw “ls: Invalid value for webhdfs parameter "op"”.
