Nobuaki Sukegawa updated SPARK-45468:
-------------------------------------
Description:
Currently, proxies can be made transparent for hyperlinks in Spark web UIs with
spark.ui.proxyRoot or X-Forwarded-Context header alone. However, HTTP redirects
(such as job/stage kill) currently requires explicit spark.ui.proxyRedirectUri
as well for handling proxy. This is not ideal as proxy hostname may not be
known at the time configuring Spark apps.
This can be mitigated by 1) always prepending spark.ui.proxyRoot to redirect
path for those proxies that intelligently rewrite Location headers and 2) by
using path without hostname (/jobs/, not https://example.com/jobs/) for those
proxies without Location header rewrites. Then redirects behavior would be
basically the same way as other hyperlinks.
Regarding 2), while hostname was originally required in RFC 2616 in 1999, since
RFC 7231 in 2014 hostname can be formally omitted as most browsers already
supported it (it is rather hard to find any browser that doesn't support it).
