Elek, Marton commented on HDFS-12961:
-------------------------------------
Patch is uploaded. To test:
1. First of all check ksm/scm ui in the usual way. It works as before.
2. Try it out with a reverse proxy:
I tested with caddy (single binary webserver) with the following config:
{code}
http://localhost:1234 {
tls off
proxy /scm http://localhost:9876 {
without /scm
}
proxy /ksm http://localhost:9874 {
without /ksm
}
}
{code}
And starting the server:
{code}
./caddy -conf Caddyfile
{code}
Webui worked with http:/localhost:1234/scm and http:/localhost:1234/ksm (and
also with the normal way: http://localhost:9874)
> Ozone: Use relative resource urls in KSM/SCM web ui
> ---------------------------------------------------

> Key: HDFS-12961
> URL: https://issues.apache.org/jira/browse/HDFS-12961
> Project: Hadoop HDFS
> Issue Type: Sub-task

>
> The current SCM/KSM web ui (+namenode/datanode) uses absolute urls:
> Css is defined as /static/..., http calls use /jmx as url, etc.
> This is problem with typical cloud native environments where some components
> could be behind a reverse proxy.
> For example in kubernetes the component could be accessible via the kubctl
> proxy and specific url:
> http://localhost:8001/api/v1/namespaces/default/services/ozonetest-http-ksm:web/proxy/
> This url points to the scm web ui but all of the resources are loaded from
> http://localhost:8001 as we use absolute urls.
> I suggest to use relative url everywhere. It could work both with standalone
> cluster (were the default context is the /) and with proxied environment
> (where the scm location could be different).
