[jira] [Updated] (SOLR-12087) Deleting shards sometimes fails and
causes the shard to exist in the down state
[ https://issues.apache.org/jira/browse/SOLR-12087?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jerry Bao updated SOLR-12087:
-----------------------------
Description:
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.

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