-----------------------------------
Summary: 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
Components: HDFS-7240
Reporter: Elek, Marton
Assignee: Elek, Marton
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).
