             Summary: Setting SOLR_HOST_ADVERTISE to start tool gives deprecation warning
                 Key: SOLR-18337
                 URL: https://issues.apache.org/jira/browse/SOLR-18337
             Project: Solr
          Issue Type: Bug
          Components: cli
         Environment: Windows
            Reporter: Mikael Sterner


If you set the {{SOLR_HOST_ADVERTISE}} environment variable before calling {{solr.cmd start}}, deprecation warnings are printed:

{noformat}
set SOLR_HOST_ADVERTISE=myhost.example.com
solr-10.0.0-slim\bin\solr.cmd start --user-managed
WARN  - 2026-08-05 12:31:59.187; org.apache.solr.common.util.EnvUtils; You are passing in deprecated system property host and should upgrade to using solr.host.advertise instead.  The deprecated property support will be removed in future version of Solr.
{noformat}
 
Expected would be no deprecation warning, as this is the correct environment variable from {{solr.in.cmd}}.

This looks like an omission in SOLR-15442 that it didn't update {{SOLR_HOST=host}} in {{EnvToSyspropMappings.properties}} when adding {{host}} to {{DeprecatedSystemPropertyMappings.properties}}, or possibly a midflight collision with SOLR-17864 if the latter should have fixed this when swapping out {{SOLR_HOST}} for {{SOLR_HOST_ADVERTISE}} in {{EnvToSyspropMappings.properties}}.
