Description

We use to backup and restore one of our collections in solrCloud.
if not to restore collection but to create it and fill from application - the second attempt to renew application index is successful both on leader and followers. But is to restore collection and then to renew index from application - we have new index on follower and old index on leader.
The Reload on collection helps to make index up-to-date on leader.
In logs we have o.a.s.u.p.DistributedUpdateProcessor Ignoring commit while not ACTIVE - state: BUFFERING replay: false
If to restart solr service before collection update from application - index on all solr servers is updated.
