---------------------------------------
Component/s: (was: Backup/Restore)
> Schema Changes are Not Visible after Reuse of ConfigSet
> -------------------------------------------------------
>
> Key: SOLR-15478
> URL: https://issues.apache.org/jira/browse/SOLR-15478
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: configset-api
> Affects Versions: 8.8
> Reporter: Steffen Moldenhauer
> Priority: Major
>
> After restoring a backup that reuses a previously existing config set,
> changes in the schema are not visible in the schema API.
> The changes will become visible only after a server restart.
> *Steps To Repeat*
> start solr server in cloud mode with SOLR_OPTS set to
> -Dsolr.disableConfigSetsCreateAuthChecks=true
> -Dsolr.allowPaths=/var/solr_backup
> solr start -c
> For preparation create a config set, collection and backup:
> [http://localhost:8983/solr/admin/configs?action=CREATE&name=testcollection&baseConfigSet=_default]
> [http://localhost:8983/solr/admin/collections?action=CREATE&collection.configName=testcollection&name=testcollection&numShards=1]
> [http://localhost:8983/solr/admin/collections?action=BACKUP&location=/var/solr_backup&name=testcollection_backup&collection=testcollection]
>
> Check the list of fields with the schema API:
> [http://localhost:8983/solr/testcollection/schema/fields]
> Note the fields listed.
>
> Simulate a schema change - add a field "test1"to the managed-schema:
> /var/solr_backup/testcollection_backup/zk_backup/configs/testcollection/managed-schema
> <field name="test1" type="string" indexed="true" stored="true" />
>
> Delete the collection and config set and restore it from the backup:
> [http://localhost:8983/solr/admin/collections?action=DELETE&name=testcollection]
> [http://localhost:8983/solr/admin/configs?action=DELETE&name=testcollection]
> [http://localhost:8983/solr/admin/collections?action=RESTORE&location=/var/solr_backup&name=testcollection_backup&collection=testcollection]
>
> Check the list of fields with the schema API again:
> [http://localhost:8983/solr/testcollection/schema/fields]
> The added test1 field is missing.
>
> The field is immediately visible in 8.6.3 In 8.8.2 a server restart is
> necessary to see the new field.
