Mark Miller updated SOLR-8069:
------------------------------
    Summary: Ensure that only the valid ZooKeeper registered leader can put a replica into Leader Initiated Recovery.  (was: Leader Initiated Recovery can put the replica with the latest data into LIR and a shard will have no leader even on restart.)

> I've seen this twice now. Need to work on a test.
> When some issues hit all the replicas at once, you can end up in a situation where the rightful leader was put or put itself into LIR. Even on restart, this rightful leader won't take leadership and you have to manually clear the LIR nodes.
> It seems that if all the replicas participate in election on startup, LIR should just be cleared.
