Amrit Sarkar commented on SOLR-8953:
------------------------------------
Just skimming,
{code}
CdcrLeaderStateManager.this.setAmILeader(props.get("core").equals(core.getName()));
{code}
The core name is in format: {{collection_shardX_replicaY}}, {{core node name}}
is saved in ZK state info for that particular collection but SolrCore doesn't
have any node name field or a mapping. Not sure what to replace
{{core.getName())}} to equate if we utilise the core node name.
> CDCR leader detector uses core name instead of core node name

> Components: CDCR, SolrCloud
> Affects Versions: 6.0
> Reporter: Shalin Shekhar Mangar
> Fix For: 6.2, 7.0

>
> CdcrLeaderStateManager should use core node name instead of core name to
> determine if current node is the leader otherwise when all replicas have the
> same name (e.g. "collection1") then it will cause cdcr processes to start on
> every replica.
