Cao Manh Dat created SOLR-11011:
-----------------------------------

             Summary: Assign.buildCoreName can lead to error in creating a new core when legacyCloud=false
                 Key: SOLR-11011
                 URL: https://issues.apache.org/jira/browse/SOLR-11011
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Cao Manh Dat
            Assignee: Cao Manh Dat


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, it lead to a failure.
