--------------------------------------
Summary: Solr RESTORE api doesn't wait for the restored collection
to be fully ready for usage
Key: SOLR-9598
URL: https://issues.apache.org/jira/browse/SOLR-9598
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Affects Versions: 6.2
Reporter: Hrishikesh Gadre
As part of the RESTORE operation, Solr creates a new collection and adds
necessary number of replicas to each shard. The problem is that this operation
doesn't wait for this new collection to be fully ready for usage (e.g. querying
and indexing). This requires extra checks on the client side to make sure that
the recovery is complete and reflected in cluster status stored in Zookeeper.
e.g. refer to the backup/restore unit test for this check,
https://github.com/apache/lucene-solr/blob/722e82712435ecf46c9868137d885484152f749b/solr/core/src/test/org/apache/solr/cloud/AbstractCloudBackupRestoreTestCase.java#L234
Ideally this check should be implemented in the RESTORE operation itself.
