----------------------------------------
Summary: proxy support for cross-machine links in master/RS UI
Key: HBASE-21825
URL: https://issues.apache.org/jira/browse/HBASE-21825
Project: HBase
Issue Type: Improvement
Reporter: Sergey Shelukhin
Follow-up to HBASE-21824. MasterStatusServlet needs to pass the current request
URL to the template. Other than having to explicitly specify the proxy URL
format (what if there are several proxies?), the best way to approach this
seems to be for the above (optionally, if enabled) to check if URL authority
includes the current server name; if not, do a string search for the server
name and port in the URL. If found, create a URL format string to be used for
all the links to other masters and RSes.
E.g. if current URL is MASTERMACHINE:12355/master-status, nothing needs to be
done.
If it's 127.0.0.1:12355/master-status, similarly there's nothing to replace.
If it's e.g. myproxy/foo/server/MASTERMACHINE/port/12355/master-status, RS link
might be
myproxy/foo/server/RSMACHINE/port/12356/rs-status.
It can be disabled by default to avoid false positives.
