Timothy Potter created SOLR-11556:
-------------------------------------
Summary: Backup/Restore with multiple BackupRepository objects
defined results in the wrong repo being used.
Key: SOLR-11556
URL: https://issues.apache.org/jira/browse/SOLR-11556
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: Backup/Restore
Affects Versions: 6.3
Reporter: Timothy Potter
I defined two repos for backup/restore, one local and one remote on GCS, e.g.
{code}
<backup>
<repository name="hdfs"
class="org.apache.solr.core.backup.repository.HdfsBackupRepository"
default="false">
...
</repository>
<repository name="local"
class="org.apache.solr.core.backup.repository.LocalFileSystemRepository"
default="false">
<str name="location">/tmp/solr-backups</str>
</repository>
</backup>
{code}
Since the CollectionHandler does not pass the "repository" param along, once
the BackupCmd gets the ZkNodeProps, it selects the wrong repo!
The error I'm seeing is:
{code}

{code}
Notice the Local backup repo is being selected in the BackupCmd even though I
passed repository=hdfs in my backup command, e.g.
{code}
curl
"http://localhost:8983/solr/admin/collections?action=BACKUP&name=foo&collection=foo&location=gs://tjp-solr-test/backups&repository=hdfs";
{code}
I think the fix here is to include the repository param, see patch. I'll fix
for the next 7.x release and those on 6 can just apply the patch here.
