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.
