> Here are the case
> {code}
> shard1 : {
> node1 : shard1_replica1,
> node2 : shard1_replica2
> }
> {code}
> node2 go down, autoAddReplicasPlanAction is executed
> {code}
> shard1 : {
> node1 : shard1_replica1,
> node3 : shard1_replica3
> }
> {code}
> node2 back alive, because shard1_replica2 is removed from {{states.json}} so
> that core won't be loaded ( but it won't be removed neither ). Then node1 go
> down, Assign.buildCoreName will create a core with name=shard1_replica2 which
> lead to a failure.
