[jira] [Created] (SOLR-12087) Deleting shards sometimes fails and causes the shard to exist in the down state

JIRA jira@apache.org
Jerry Bao created SOLR-12087:
--------------------------------

             Summary: Deleting shards sometimes fails and causes the shard 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


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.

It seems like when deleting replicas, ZK writes are timing out, preventing the cluster state from being properly updated.
