> Deleting replicas sometimes fails and causes the replicas to exist in the
> down state
> ------------------------------------------------------------------------------------
>
> Key: SOLR-12087
> URL: https://issues.apache.org/jira/browse/SOLR-12087
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: SolrCloud
> Affects Versions: 7.2
> Reporter: Jerry Bao
> Priority: Major
>
> Sometimes when deleting replicas, the replica fails to be removed from the
> cluster state. This occurs especially when deleting replicas en mass; the
> resulting cause is that the data is deleted but the replicas aren't removed
> from the cluster state. Attempting to delete the downed replicas causes
> failures because the core does not exist anymore.
> This also occurs when trying to move replicas, since that move is an add and
> delete.
