Larry McCay commented on KNOX-626:
----------------------------------
I've attached a patch to change the parsing of the query string done through
HttpUtils.
While it seems that the specific issue reported here in the last comment from
[~sumit.gupta] is certainly wrong parsing behavior, I am concerned that I had
to change many of the tests in HttpUtilsTest to accommodate what I expect to be
proper semantics.
The fact there are tests for very specific patterns makes me concerned that
they were encountered in proxying of UIs or something.
I would really appreciate a review from someone as a sanity check.

> When using the HDFSUI service, the proxied NameNode UI does not function
> correctly for the following tabs, Overview, Datanodes, Datanode volume
