------------------------------------------
Summary: 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: Backup/Restore, configset-api
Affects Versions: 8.8
Reporter: Steffen Moldenhauer
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.
