>          Issue Type: Improvement
>          Components: SolrCloud
>    Affects Versions: 9.0, 9.1
>            Reporter: Pierre Salagnac

> After a Solr node restart, shard leader election code has specific calls to Zookeeper to wait for all replicas to join the election.
> This code is useless when joining leader election for another reason than node restart.
> (in class ShardLeaderElectionContext, call to method areAllReplicasParticipating() is useless and we ignore the returned value).
