Mano Kovacs commented on SOLR-11417:
------------------------------------

bq. I'm not sure its preferable to have a replica disable it's own ability to 
be a leader - kind of defeats the repeated attempts.
Agreed. Going with that approach.

> Crashed leader's hanging emphemral will make restarting followers stuck in 
> recovering

> If replicas are starting up after leader crash and within the ZK session 
> timeout, replicas
> * will lose leader election due to hanging ephemerals
> * will read stale data from ZK about current leader
> * will fail recovery and stuck in recovering state
> If leader is down permanently (eg. hardware failure) and all replicas are 
> affected, shard will not come up (see also SOLR-7065).
> Tested on 6.3. See attached image for details.
